HELPP I DONT GET IT. WXPLAIN AND ANSWER PLEASE:(((

Let f (x) = x4 - 4x3 - 2x2 + 12x + 9, g(x)_ vx2 _ 2x_3 and (2 + 1 RX(X ) = x2 _ 2X - 3 Part A: Use complete sentences to compare the domain and range of the polynomial function f (x) to that of the radical function g(x). (5 points) Part B: How do the breaks in the domain of h(x) relate to the zeros of f (x)? (5 points)
