Question

Which is an apparent factor of the quadratic function graphed below? A. (x + 3) B. (x - 1) C. (x-3) D. (x + 4)

Answer 1

Let's get the x value of the choices given applying additive and subtractive inverse property,

A.) x + 3; x + 3 - 3 = 0 - 3 ; x = -3

B.) x - 1 ; x - 1 + 1 = 0 + 1 ; x = 1

C.) x - 3 ; x - 3 + 3 = 0 + 3 ; x = 3

D.) x + 4 ; x + 4 - 4 = 0 - 4 ; x = -4
