Answer:
once
Step-by-step explanation:
The vertical line test shows how many outputs (y-value) there are for one input (x-value). There can only one output for each input because only one value should satisfy an equation that represents a function. If the vertical line goes through the graph twice, that shows there are two outputs for a single x-value. This would mean it is not a function.
