Function Notation is an easy way to display the input of a function. The f(x) is f of x and displays the input of the function.
The f(x) is f of x and not f times x
f is used most often but any letter can be used.
When you evaluate a function you simply plug in the value for x into the output.
For example,
Evaluate f(x) = 2x + 5 If x =5 then you have f(5) = 2(4) + 5
