Answer: choice C) Yes, because it passes the vertical line test
---------------------------------------------
---------------------------------------------
Step-by-step explanation:
The vertical line test is a test to see if it is possible to pass a single vertical line through more than one point on the curve. Since it is not possible to do so, the curve has passed the vertical line test. Passing the vertical line test indicates we have a function. Any x value you plug in will produce exactly one (and only one) y value. If the graph failed the vertical line test, then an x value would produce more than one y values which goes against what a function is.
