Mr. walker gave his class the function f(x) = (x 3)(x 5). four students made a claim about the function. each student’s claim is
below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim is correct?
We are given with the function f(x) = (x - 3)(x - 5) Which has x-intercepts of (3,0) and (5,0) The y-intercept is y = 15 The vertex is at (4, -1) The midpoint between the x intercepts is (4,0)
