I really need help with these practice questions please.

5. Notice that if we apply the definition of the dervative f'(a) = lim flat h) - f(@ to f(x) = et and h-0 a = 0 we get the limit: 20th _ 20 lim = lim eh - 1 h h-+0 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 f(r) and a. Determine the function f(x) and the value a for the following limit: lim [2(3 + h)2 - (3 + h)] - 15 h4. Use the following graph of y = 112:) to sketch the graph 1; = f'(:r}. In your solution, please highlight the points corresponding to (1, 1.25), (0, 1}, (1, 1.25). ___ 'E' |_|
