Question

6. Is the following
graph a function? Explain your
answer.

Answer 1

• Yes, it is a function

Explanation:

As per definition of a function, each x-value has to have exactly one y-value assigned.

Graphs are verified with the vertical line test. If there are two or more points on any vertical line that cuts the graph then this is not a function. If the graph passes this test then it is a function.

The given graph represents a function.
