Identify the range of the following relation:

• {-6, 14, 2, 28}

• {-6,14, 0, 32, 2, 38, 4,44}

• {-6, 0, 2, 4}

• {14, 32, 38, 44}

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.
