Im having some trouble with a question, where i need to differentiate a function, and then find the equation with for the tangent line with maximum slope. What steps do i need to follow to find this?

Is it function of single variable [e.g. y = f(x)] or multiple-variable [e.g. z = f(x,y)]?

Assuming that you have a function of a single valued function, y= f(x), the first thing you would do is take the derivative of y, y'= df/dx which gives the slope of the tangent line at any x. Then look for the maximum slope. You have probably learned that the (local) maximum value of a differentiable function occurs where its derivative is 0. So if f is twice differentiable, differentiate it again! The point where f''(x)= 0 must be either a (local) maximum or minimum of f'(x). (Check to be sure it is a maximum and not a minimum.). Once you have found that value of x, \(\displaystyle x_0\), the tangent line to y= f(x) there is \(\displaystyle y= f'(x_0)(x- x_0)+ f(x_0)\).

How do you find the maximum slope of a function? ›

How do you find the steepest slope of a function? Take its derivative and look for the largest and smallest (most negative) value you can get out of out that function. The derivative is the gradient of the curve.

What is maximum slope? ›

The absolute largest positive or negative slope will be the slope chosen. This is the Maximum Slope, and is plotted with the red slope line.

How do you find the minimum slope of a function? ›

Answer and Explanation:
  1. Differentiate the function to find the slope-function z = f ′ ( x ) for the given function.
  2. Now, you need to find the minimum value of the derivative of the function. ...
  3. Test the critical points to check the minimum condition of the slope-function by substituting those values into the.

How do you find the maximum function? ›

The maximum/minimum of a function are the points where the first derivative (the gradient) of the function is zero. So with a function of the form y=f(x), you must take the derivative (dy/dx) and set your result equal to zero.

What is maximum and minimum slope? ›

If the slope of a graph is positive: The line of maximum slope will be from the lower right corner. of the left point to the upper left corner of the right point. The line of minimum slope will be from the upper left corner. of the left point to the lower right corner of the right point.

How do you find the maximum and minimum of a function on a graph? ›

By looking at the y-values for each of these points, we can identify the absolute maximum of the graph as the point with the highest y-value, and we can identify the absolute minimum as the point with the lowest y-value.

What is the maximum slope of a graph? ›

This is the steepest line that crosses all of the error bars. (Actually it touches each of the error bar rectangles, which is the important thing.) It's called the line of maximum slope. Since it has a positive slope, it will have a minimum y-intercept.

What is the maximum slope for a fill slope? ›

Slopes for permanent fill shall be not steeper than one unit vertical in two units horizontal (50-percent slope).

What is the maximum slope on a finished grade? ›

Most places have a maximum slope between 10% and 18%. Any slope above 15% is considered steep. Look at local requirements to see what your municipality allows.

How do you find the minimum and maximum? ›

Finding Maxima & Minima
  1. Find the derivative of the function.
  2. Set the derivative equal to 0 and solve for x. This gives you the x-values of the maximum and minimum points.
  3. Plug those x-values back into the function to find the corresponding y-values. This will give you your maximum and minimum points of the function.

What is the maxima of a function? ›

The place in a given interval where the values of the function near that point are always less than the value of the function at that point is known as a local maxima. Local minima, on the other hand, are points where the function's values around that point are bigger than the function's value at that point.

What is the maximum and minimum of a function? ›

In mathematical analysis, the maximum and minimum of a function are, respectively, the largest and smallest value taken by the function. Known generically as extremum, they may be defined either within a given range (the local or relative extrema) or on the entire domain (the global or absolute extrema) of a function.

How do you find the maximum on a graph? ›

The maximum value of a graph is the point where the y-coordinate has the largest value. The minimum value is the point on the graph where the y-coordinate has the smallest value.

What is the max function and if function? ›

The MAX is an inbuilt Statistical function, and the IF is an inbuilt Logical function of the Functional library, so we can insert the formula or enter them directly in the worksheet. For example, we will calculate the maximum value according to criteria using the MAX IF Function.

What is the formula for the maximum of two functions? ›

Let f be a function of two variables x and y. We say that f has a local maximum at (a, b) if f(x, y) ≤ f(a, b) for all points (x, y) in a neighbor- hood of (a, b). We say that f has a local minimum at (a, b) if f(x, y) ≥ f(a, b) for all points (x, y) in a neighborhood of (a, b). critical point is (0,0).

Can you have more than 100% slope? ›

Note that slopes can exceed 100 percent (see +148% in Figure 1.5). When a slope equals 100 percent, it simply means that the rise is equal to the run.

Can slope be higher than 1? ›

Yes, the slope can have a value greater than one. It means that the line would have a very steep slope. To illustrate, if the value of m = 3 2 , this means that the graph goes up three units and goes forward by two units. The slope here is 3 2 > 1 .

What does 100% slope mean? ›

A rise of 100 feet over a run of 100 feet yields a 100 percent slope. A 50-foot rise over a 100-foot run yields a 50 percent slope. Another way to express slope is as a slope angle, or degree of slope.
