Answer:
F(x)=4 means you plug in the 4 into where the variable is.
Step-by-step explanation:
Not really sure what your question meant but If you trying to find a problem with f(x)=4, then you plug in 4 into the variable of x.
First make and equation. Since you want to find the number of the day where both charge the same total amount, you would make the equation:
let x= the number of days
110+46(x)=70+54(x)
Solve:
110-70+46(x)=70-70+54(x)
40+46(x)=54(x)
40+46(x)-46(x)=54(x)-46(x)
40=8(x)
40/8=8x/8
5=x
Therefore your answer would be 5 days
