which is an x - intercept of the graphed function? (0, 4) (-1, 0) (4, 0) (0, -1)
which is an x - intercept of the graphed function? (0, 4) (-1, 0) (4, 0) (0, -1)
Answer
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
For option (0, 4), y = 4, not an x - intercept. For option (-1, 0), y = 0 and it is on the x - axis. For option (4, 0), from the graph, the function does not cross x - axis at x = 4. For option (0, -1), y=-1, not an x - intercept.
Answer:
(-1, 0)
