Answer to Question #130102 in Calculus for neha

Question

A curve is the graph of a function  if and only if NO vertical line intersects the curve more than once. true or false

Answer 1

True.

In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. If a vertical line intersects a curve on the xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function.
