MAT 0460 PREP FOR LINEAR AND QUADRATIC FUNCTIONS Factor the following quadratic functions. f (x) =x2+6x -16 g(x) = x2-14x-72 g(x) = 2x2+5x +3 h(x) = 5x2 -17x+6 Determine the x-intercepts for each quadratic function. f (x) = x2 - x-30 f (x) = 6x2 -5x-4 Vertex form of a quadratic f (x) = a(x - h)2 + k, where (h, k) are the coordinates of the vertex. It opens upward when a > 0 and downward when a 0 and downward when a
