Write an equation for the translation of x^2+y^2=16 by 8 units left and 3 units down

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?

What statement is true? 2x^2-9x+2=-1

How is working backward similar to solving an equation?
