Is this a function? Explain.

• Yes; it passes the horizontal line test.

• No; it is not a straight line.

• Yes; it passes the vertical line test.

• No; it does not pass the vertical line test

Which graph does NOT pass the vertical line test?

Which graph does NOT pass the vertical line test?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

The vertical line test determines if a ​ (a)   is a function by showing visually that every x value has only one ​ (b)   (y value)
