Question

question 8 of 10
does this graph represent a function?
a. no, because some of the y-values are paired with two x-values
b. yes, because it touches the y-axis exactly one time
c. yes, because each x-value has exactly one corresponding y-value
d. no, because there are no closed circles to show where the graph ends

Explanation:

A function is defined as a relation where each input (x - value) has exactly one output (y - value). The vertical line test can be used to determine if a graph represents a function. If a vertical line drawn anywhere on the graph intersects the graph at most once, then it is a function. In this graph, for every x - value, there is exactly one corresponding y - value.

Answer:

C. Yes, because each x - value has exactly one corresponding y - value
