Power Rule at a Point (Video)

This video goes through the different versions of the power rule and how they can be used to find the derivative of a polynomial function, or a rational function with a negative exponent.

Complete the following assignment for classwork. There is space for you to show your work, here you should show the derivative and your substitution.

Step 1: Find the derivative of the function

Step 2: Sub in the value to find the gradient at that point

Step 3: Find your answer at the bottom of the page to fill out the code.
