Question

Does this graph represent a function? Why or why not? A. No, because it is not a straight lineB. No, because it fails the vertical line test C. Yes, because it passes the vertical line test D. Yes, because it is a curve

Answer 1

It is important to know that a function has to pass the vertical line test, which is about drawing a vertical line across the function. If this vertical line inercepts more than one point of the function, then the graph doesn't represent a function.

Hence, it's not a function because it fails the vertical line test.The answer is B.
