I really need help with these practice questions pleasee.

4. Use the following graph of y = x) to sketch the graph 3; = f"(n:}. In your solution, please highlight the points corresponding to (1,1.25),(D, 1}, (1, 1.25). 5. Notice that if we apply the denition of the dervative 3"(a) = ilainh w to f(:c) = e2 and -+ a = 0 we get the limit: e+"e , ehl 531'}: h :33}: h We say that these limits represent the derivative of y = e' at a = 0. In this question, you will apply this process in reverse. Given a. representation of a derivative, you'll determine the function r) and a. Determine the function f(:r) and the value a for the following limit: Hm [2(3 + h)2 (3 + h)] 15 h-I-O h
