Question

Which function’s graph has a y-intercept of 1.5?

A. f(x) = 3x + 2 B. f(x) = 1.5(2)x C. f(x) = 1.5(2)x + 1 D. f(x) = 0.5(2)x + 1.5

Answer 1

D)

Explanation:

for each equation, substitute zero for 'x' and solve for 'y' (this will be the y-int)

A) y-int = 2

B) y-int = 0

C) y-int = 1

D) y-int = 1.5
