Function

Step-by-step explanation:

We can tell if the graph is function or not by doing line test.

First, we draw a vertical line.

Second, if the graph intercepts the line more than two points then it won't be a function.

If the graph only intercepts the line only once (one point) then It is a function.

From the graph, It is a function.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
