Question

Raphael graphed the functions g(x)=x+2 and f(x)=x−1. How many units below the y-intercept of g(x) is the y-intercept of f(x)?

A coordinate plane with 2 lines drawn. The first line is labeled f(x) and passes through the points (0, negative 1) and (1, 0). The second line is labeled g(x) and passes through the points (negative 2, 0) and (0, 2).

−3 units
−1 units
2 units
3 units

Answer 1

g(0) = 2 and f(0) = -1. The difference is 2 - (-1) = 3, so the y-intercept of f is 3 units below that of g.

Answer: 3 units.
