For the function y = f(x), the solutions to the equation 0 = f'(x) are x = -3,0,2 and the solutions to the equation 0 - f"(x) are x= -1, 2. Furthermore, f"(-2) = 7, f"(1) = -9, and f"(3) = 4.

a. Where does y = f(x) have a relative maximum and where does y = f(x) have a relative minimum?

b. Where does y= f(x) have an inflection point?

Would love some help with this, I don't even know where to begin!
