Question

What is the range of the given function? {(–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)}

Answer 1

In the attachment I have answered this problem.

Concept:

Range of a function f is the set all images under f in codomain.

See the attachment for detailed solution

Answer 2

Range of a function f is the set all images under f in co-domain.

Given: f{(-2, 0), (-4, -3), (2, –9), (0, 5), (–5, 7)}

We will now have, f ( -2 ) = 0

f ( -4 ) = -3

f ( 2 ) = -9

f ( 0 ) = 5

f ( -5 ) = 7

Therefore, the range of f = {-9, -3, 0, 5 , 7}
