Question

What is the range of the following list of ordered pairs? (-4,-2),(3,5),(0,4)

Answer 1

Range is the y-value. The y-value in an ordered pair is the second number

(x, y)

So pick out all the y-values from the given ordered pairs:

(-4, -2) -> -2
(3, 5) -> 5
(0, 4) -> 4

Now put them together.

The range is {-2, 4, 5}
