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; there is a line connecting the dots.

What test is used to determine if a graphed relation is a function?

• The Vertical Line Test

• The Horizontal Line Test

• The Diagonal Line Test

• The Litmus Test

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

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
