Answer:

"Vertical line test"

Step-by-step explanation:

the vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. If the line goes through 2 or more points, your line is not a function

To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Hope this helps.Have a blessed day!
