Joey decided to start a lawn care business. He charges customers $25 per hour, plus
a $75 service fee for each visit, which can be represented by the function
f (x) = 25x + 75. In the equation, what is represented by f(x)?
a function just shows you that f(x) = y and the x in brackets isn't supposd to be multipled by f but rather it shows you what x will be. In this case y=25(4)+75.
