Question

What is the range of this function?

A. {-4, -1, 4}
B. {-4, 1, 3}
C. {-4, -1, 1, 3}
D. {-4, 1, 3, 4}

Answer 1

B. {-4, 1, 3}

Explanation:

The range of a function is the set of y-coordinates.

The function has three points: (-5, -4), (-1, -4), (0, 1), (4, 3)

There are 3 different values of y-coordinates: -4, 1, 3

The set that contains the three values of the y-coordinates is {-4, 1, 3}.

Answer: B. {-4, 1, 3}
