Question

A function is represented by these ordered pairs: {(9,-3), (10,-2), (-1,-3), (0,-2), (2,2), (-1,-1)}. How many elements are in the range of the function?

A. 3
B. 4
C. 5
D. 6

Answer 1

The range of the function is the set of all possible y-values. For the given function, the range contains 4 elements: -3, -2, 2, and -1.

Step-by-step explanation:

A function is represented by a set of ordered pairs. The range of a function refers to the set of all possible y-values of the function. To find the range, we need to identify all the unique y-values in the given set of ordered pairs.

For the given function {(9,-3), (10,-2), (-1,-3), (0,-2), (2,2), (-1,-1)}, the y-values are -3, -2, 2, and -1. So, the range of the function contains 4 elements: -3, -2, 2, and -1.

Therefore, the correct answer is B. 4.
