Given the two functions f and h such that f(x) = x3 -3x2 -4x +12 and f (x ) for x * -2 h(x) =x+2 P, for x = -2 a Find all zeros of the function f. b ) Find the value of p so that the function h is continuous at x = -2. Justify your answer. C) Using the value of p found in b), determine whether h is an even function. Justify your
