Be careful at x =2. Answer: YES This is not a function . Worksheet (Algebra) Answer Key: No . That is, every x-value of a function must be paired to a single y-value. A function can only have one output, y, for each unique input, x.If a vertical line intersects a curve on an 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.
