Given that XY=ZY, WX=6x-1, and XZ= 10x+16, find ZW

Iam so stuck. what is the worked out answer for this question?

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?

Which of the following is true for the relation f(x)=2x^2+1
