Answer:
[tex]f(1)=11,f(2)=20,f(3)=29[/tex]
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.
Step-by-step explanation:
Given:
The total charge for babysitting for [tex]t[/tex] hours is given as:
[tex]f(t)=2+9t[/tex]
We need to find the function values for [tex]t=1,2,3[/tex]. [tex]f(1)=2+9(1)=11\\f(2)=2+9(2)=2+18= 20\\f(3)=2+9(3)=2+27=29[/tex]
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.
