Question

What is the range of the function represented by these ordered pairs?

{(–2, 1), (0, 0), (3, –1), (–1, 7), (5, 7)}
{–2, –1, 0, 3, 5}
{–1, 0, 1, 7}
{–2, –1, 0, 1, 3, 5, 7}
{0, 1, 7}

Answer 1

B

Explanation:

We are given the points [ (–2, 1), (0, 0), (3, –1), (–1, 7), (5, 7) ]

The range is all possible y-values in the function.

1, 0, -1, 7, 7

Put them in order and take out any duplicate numbers.

-1, 0, 1, 7

Best of Luck!

Answer 2

• {-1, 0, 1, 7}

Explanation:

Set of ordered pairs

• {(–2, 1), (0, 0), (3, –1), (–1, 7), (5, 7)}

Range of the function is the second numbers of the pairs:

• 1, 0, - 1, 7, 7

Putting them in set notation in ascending order and ignoring duplicates:

• {-1, 0, 1, 7}
