Question

Bev earns $2 a week for taking out her neighbor’s trash cans. Complete the table of values. Then state the domain and range.

Answer 1

Domain : $\{1,2,3,4\}$

Range: $\{2,4,6,8\}$

Explanation:

It is given that Bev earns $2 a week.

Thus, for n number of weeks, we shall multiply $2 with n.

Where $n=1,2,3,4$ is the number of weeks.

For 1 week, Bev earns $2n=2(1)=2$ ⇒ $2

For 2 weeks, Bev earns $2n=2(2)=4$ ⇒ $4

For 3 weeks, Bev earns $2n=2(3)=6$ ⇒ $6

For 4 weeks, Bev earns $2n=2(4)=8$ ⇒ $8

Thus, we can see that the domain is the number of weeks.

Hence, Domain : $\{1,2,3,4\}$

Also, the money earned is the range.

Hence, Range: $\{2,4,6,8\}$
