A function f has f(5) = 20, f’(5) = 2, and f”(x)

 

Expert Solution
Step 1

It is given that

                                                 f5=20f'5=2

For                                           f''x

Since the double derivative of the function is negative f''x<0 means function is concave downwards and the slope is positive at x=5 but decreasing with respect to x.
