Graph 1 is not a function because in some places, it has two y values for each x value. Graph 2 and 3 are both functions.

A good way to test for functions and non-functions on graphs is to use the "vertical line test." If you draw lines parallel to the y-axis, those lines should only pass through the graph ONCE. If at any point the same vertical line touches the graph twice or more, then it fails the test and is not considered a function.

Tom Harding is a proofreader. He is paid $0.23 for every page he proofs. What is Tom's total pay for a week in which he proofrea

natka813 [3]

Alrighty, what I was always taught was to start by writing out what you know from the question.

What I know:
-Tom is paid $0.23 for every page of proofs.
-He proofreads 1,992 pages.

In order to figure out how much money Tom has made, we need to multiply 0.23 by 1,992. Multiplying allows us to see the total amount of money made by proofreading x amount of pages - for every page he proofreads, he makes $0.23.
0.23×1992=458.16

Therefore, Tom made $458.16.

Hope this helps!
