Question

Given g(x) = - 4x + 8, identify the domain, range, and x-intercept of the function.

Domain: -< x < 0; Range: -∞ Domain: -- O Domain: -4 < x <8; Range: -4 < y < ; x-intercept (2, 0)
O Domain: -4 < x < 8; Range: -

Answer 1

y = -4x + 8

domain : (-∞ , ∞) all real numbers

range: (-∞ , ∞) all real numbers

x intercept (when y is 0): (2,0)

0 = -4x+8

-8 = -4x

x = 2
