Question

Determine if this
graph is an
example of a
function.

Answer 1

This graph is a function.

Explanation:

Passes the vertical line test. Meaning that there is only one y value to be on one x value.

If you make a T-chart with the x and y values, you will see that there is not more than one y-value for the x-value.

You can also draw vertical lines to test if there is more than one point that lies on the vertical line.

Answer 2

Yes, this graph is a function since it passes the vertical line test.
