Question

Without graphing, what is the x-intercept of this function? A) (0, 1) B) (1, 2) C) (−1, 0) D) (−2, −1)

x y
-2 -1
-1 0
0 1
1 2
2 3

Answer 1

The x-intercept of the function is C) (−1, 0).

Explanation:

The x-intercept is the point where a line crosses the x-axis. The key is realizing that the x-intercept is the point where y = 0.

From the data given, the point (-1, 0) is our x-intercept because when y = 0, we're on the x-axis.
