  1. Mαth JΣθPARδY! Mαth JΣθPARδY! Mαth JΣθPARδY! was created by GradeAmathhelp.com

  2. Mαth JΣθPARδY! A - 100 • Does the following represent a function? Explain why or why not.

  3. A-100 answer • Yes. Each input is matched with exactly one output.

  4. Mαth JΣθPARδY! A - 200 • Is the following a function? Explain why or why not.

  5. A-200 answer • No. It doesn’t pass the vertical line test. A vertical line touches the graph at two points.
