Consider the function y = 9 + 5ex Follow the steps to find dx a Determine what the inside and outside functions are. Let the insides be the variable u, then rewrite f in terms of u Insides u = Outside: y = b. Take the derivative of the inside and outside pieces. du dx dy du c. Use the chain rule (write answer in terms of x.) dy dx (write answer in terms of u) dy-du dy du dx dx du to find the derivative of the function. Write your answer in terms of x.
