What is the vertical line test?
Answer
The vertical line test is to see if the line is a function. The test is simply done by drawing one vertical line through a graph to see if it's a function. If the line passes through the graph once it is considered a function. However, if we do the vertical line test and the it passes through the graph more than once then the graph is not a function.
