To find if a graph is a function you can use the vertical line test. The vertical line test is where you place a vertical (up and down) line on the graph. If this vertical line intersects the graph more then once it is NOT a function. It is a relation. Another way to see if it is NOT a function is seeing if there are coordinates where they have the same x-value but different y-values

Graph 1: You were correct. This is NOT a function because the vertical line would cross the graph two times

Graph 2: You were correct. This is NOT a function, because there are three points that have the x-value of -4 yet the have different y-values

Graph 3: This actually is a function! It passes the vertical line test. Although there are two points that have the y-value of -2, that's okay. There are no points with the same x-value

Graph 4: You are correct. This kind of graph is called a piecewise function. It does look like there are two points that have the same x-value, but since only one circle is colored in it means that only the colored in point is "valid."

Graph 5: You are correct. This IS a function. It passes the vertical line test.

Graph 6: This is NOT a function. If you put a vertical line through the circle you will hit it at the top and at the bottom

Hope this helped!

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
