Question

Which of these lines could possibly intersect the graph of a function at more than one point? Select three that apply.

Answer 1

According to Vertical Line test, a vertical line only intersect the graph of a function at one point. Among the choices given, x = 4 is a vertical line. So this line cannot intersect the graph of a function at more than one point. The other three would apply. So the answer choices are A, C and D.
