F is a trigonometric function of the form f () = a sin(bx+c) + d. Below is the graph f (x). The function intersects its midline at (3, -6.5) and has a maximum point at (4, -2).
Find a formula for f(x). Give an exact expression.
f(x)

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 about the function is correct?
