Question

13.

EVALUATE The total charge for a babysitting job that lasts t hours can be represented by the
function (t) = 2 + 9t. Evaluate this function for the domain (1,2,3). Show your work and briefly
explain what each pair of values means in this problem situation.​

Answer 1

`f(1)=11,f(2)=20,f(3)=29`

For 1 hour of babysitting, the total charge is 11 units.

For 2 hours of babysitting, the total charge is 20 units.

For 3 hours of babysitting, the total charge is 29 units.

Explanation:

Given:

The total charge for babysitting for
`t` hours is given as:

`f(t)=2+9t`

We need to find the function values for
`t=1,2,3`.
`f(1)=2+9(1)=11\\f(2)=2+9(2)=2+18= 20\\f(3)=2+9(3)=2+27=29`

Therefore, each pair of values mean that:

For 1 hour of babysitting, the total charge is 11 units.

For 2 hours of babysitting, the total charge is 20 units.

For 3 hours of babysitting, the total charge is 29 units.
