Question

A function g is defined below.

​(a) Write g as a set of ordered pairs.

​(b) Give the domain and range of g.

g(-3)=-3,g(0)=-3,g(3) = -3

Answer 1

Hi Omar:

Here's how to do this one:

(a) ordered pairs for function g are: (-3, 3), (0, -3), and (3, -3)

(b) The domain of g is the set of allowed values inside the parentheses, namely: {-3, 0, 3}

The range of g is the set of allowed g values, namely: {-3} all the domain values map to the same range value, namely, -3.
