Question

Determine if the following graph is a function. Write the correct words that complete the sentence.

Look at the image down below.

Answer 1

Yes, the graph is a function because it passes the vertical line test

Explanation:

The vertical line test is a useful way to determine if a graph is a function or not by moving a vertical line from left to right. If it passes through more than one point at any given moment, the graph will not be a function because every input must have a unique output.
