Question

which is an x - intercept of the graphed function? (0, 4) (-1, 0) (4, 0) (0, -1)

Explanation:

Step1: Recall x - intercept definition

The x - intercept of a function is a point where the graph of the function crosses the x - axis. At an x - intercept, the y - coordinate is 0.

Step2: Check each option

We check the y - coordinate of each given point. For (0,4), y = 4; for (-1,0), y = 0; for (4,0), y = 0; for (0,-1), y=-1. Then we look at the x - values on the graph. From the graph, we can see the function crosses the x - axis at x=-1.

Answer:

B. (-1, 0)
