Question

Fernando works between 12 and 25 hours each week. The function t, where t(x) = 9.50 x represents the amount of money Fernando earns

given the number of hours, x, he works.

Answer 1

The domain of the function is = {
`12 \leq x \leq 25`}

Explanation:

Fernando works between 12 and 25 hours each week.

Hence, Fernando works either
`\geq 12` or
`\leq 25` hours of a week.

The function is given by,
`t(x) = 9.50x`

This function's domain is
`12 \leq x\leq 25`

`t(12) = 9.50*12 = 114\\t(25) = 9.50*25 = 237.5`

The range of the function is between 114 and 237.5.
