Function Practice

What is the vertical line test?

• A graph is not a function if you can draw a vertical line and it crosses the graph in more than 1 location

• A Graph is a function if it can be altered to make a linear equation.

• A graph is a function if you can create a vertical line that adheres to the equation y=mx+b

• Stay within the vertical lines
