Answer :
If the question is how much does it cost for 4 lines plus a one-time advertising fee than your answer is $36.
Answer:
The domain of the function is {1,2,3,4} and the range of the function is {$23, $26, $29, $32}
Step-by-step explanation:
Consider the provided information.
A newspaper charges $3 per line for the first 4 lines plus $20 fee to advertise.
First write the function as shown.
Let l represents the number of lines and $20 fee to advertise.
Therefore the function is: [tex]f(x)=3l+20[/tex]
For l=1
[tex]f(1)=3(1)+20=23[/tex]
For l=2
[tex]f(2)=3(2)+20=26[/tex]
For l=3
[tex]f(3)=3(3)+20=29[/tex]
For l=4
[tex]f(4)=3(4)+20=32[/tex]
Hence, the domain of the function is {1,2,3,4} and the range of the function is {$23, $26, $29, $32}
