Question

What is the range of the given function?

{(-2, 0), (-4, -3), (2, -9), (0,5), (-5, 7)}
O x
{yly = -9, -3, 0, 5, 7}
x = -9, -5, 4, -3, -2,0, 2, 5, 7
{yl y = -9, -5, 4, -3, -2, 0, 2, 5, 7}

Answer 1

9514 1404 393

Answer:

(b) {yly = -9, -3, 0, 5, 7}

Explanation:

The range is the set of y-values in the ordered pairs. It is usually convenient to list a set in alphanumeric order.

The second values of the ordered pairs are 0, -3, -9, 5, 7. So, the range is ...

y ∈ {-9, -3, 0, 5, 7} . . . . . matches the second choice
