Question

The graph of which quadratic equation is shown below?

Answer 1

y = −x2 + 6x + 8

y = −x2 − 6x + 8

y = x2 + 6x + 8

y = x2 − 6x + 8

Answer 2

x-intercepts are (0,-4) and (0,-2)

so the roots are x = -4 and x = -2

so the factors are (x+4) and (x+2)

if i multiply them..

(x+4)(x+2) = x^ 2 + 2x + 4x + 8 = x^2 + 6x + 8

does that help?

Answer 3

yeah

Answer 4

thanks it's y = x2 + 6x + 8
