Question

Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?

f(x) = −3x + 2

x y
2 | 6
2 | 10
2 | 14

A) The function f(x) has a higher y-intercept.
B) The function g(x) has a higher y-intercept.
C) They both have the same y-intercept.
D) The relationship between y-intercepts cannot be determined.

Answer 1

D-cannot be determined. g(x) is a vertical function, which is not a function. You cannot have the same x-value repeated. Because of this, g(x) has no y-intercept, and the relationship cannot be determined
