Question

Helppp!!!!!!!!!!!!!!! Which of the following is the correct equation for this function?

Answer 1

It must be choice A, because:

The graph is upside U, so there must be a negative in front of the x^2.

The graph intersects the x-axis at x = -1 and x = 3, so (x+1) and (x-3) have to be the two factors.

Answer 2

so you have y = - (x + 1)(x - 3)
