Question

5. Identify the domain and range of the functions below.

Answer 1

a.

y= lx-3l - 2

For any value of x, the function will be defined.

Domain = all real numbers

Since the function is moved 2 units down

Range = [-2;∞)

b.

Domain: the set of all possible values of x

By looking at the graph

Domain= [0,12]

Range: the set of all possible values of y.

Range: [1000,1500]
