f(x) = x - 4 → H
to find the x- intercept of a function set f(x) = 0 and solve for x
(F) x² + 2x - 8 = 0
(x + 4 )(x - 2) = 0 ⇒ x = -4, x = 2 are the x-intercepts
(G) [tex]\frac{- 3x + 16}{4}[/tex] = 0 ⇒ x = [tex]\frac{16}{3}[/tex] is the x- intercept
(H) x - 4 = 0 ⇒ x = 4 is the x-intercept
(I) (x + 4)(x - 3) = 0 ⇒ x = - 4, x = 3 are the x-intercepts
