This tells us that the function named "f" takes whatever input you give it (here represented by "x") and squares it and then subtracts 1. This function f will square any input and then subtract 1.

f(a) is what you get from f when you give it an input of "a". And what does f do to its input? Answer: It squares it and then subtracts 1. So:

For f(a)-3 we just take f(a) and then subtract 3:
