Question

Sasha sells T-shirts. Each day she earns a set amount, plus a commission.

(Look at the table below)

Which is a reasonable domain for the function Sasha uses to determine her pay?

A. all real numbers

B. 0 < x < 3

C. 0 < x < 50

D. 68 < x < 80

Answer 1

Domain → 0 < x < 5

Explanation:

Sasha sells T-shirts and earns a fixed amount plus a commission by selling each shirt. (As given in the table)

Table attached shows a linear function (A regular increase in total pay with the increase in number of shirts sold)

So the input values of the table (Number of shirts sold) will represent the domain of the linear function.

Hence, reasonable domain for the function will be → 0 < x < 5
