Please solve this problem.PLEASE READ CAREFULLY: I have ask here for 2 times and the answer always DNE. However, I've check with my teacher and it's not. Then we need to find another solution that can use every material here.

Suppose that f() is a function that is continuous on the interval [-5, 5]. The derivative of f() on the interval [-5, 5] is given by f'(3) = 12x2 + 2, x > 4, 16x, x
