Function notation is an alternate for 'y' notation. That is, f(x) = something is also shown as y = something. The f(x) notion makes it clear the value of f(x) is dependent on the value of x, whereas, 'y' notation gives the impression they're independent.
.
The function we have here is a 'cube machine.' You put a value of 'x' into the machine and out comes the cube x*x*x. Of course, we show x*x*x as .
.
Given
.
f(5) simply means x=5.
.
.
So we can say the 5 cubed = 125.
Done.
