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?

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined
