Question

Compare the x-intercepts for the two linear functions represented below.

Answer 1

Answer:

B. The x-intercept of function A is less than that of function B.

Step-by-step explanation:

Both functions have y-intercepts of -1. Function A has a slope of 2, while function B has a slope of 1. Since Function A has a steeper slope, its x-intercept will be closer to x=0 than that of Function B.

___

The x-intercept of Function B is given as (1, 0). The x-intercept of Function A can be found by solving for x when y=0:

... 0 = 2x -1

... 0 = x - 1/2 . . . . divide by 2

... 1/2 = x . . . . . . . the x-intercept is (1/2, 0), so is less than (1, 0)
