Answer:
The notation "f(x)" is exactly the same thing as "y"
Step-by-step explanation:
The effect of using f(x) instead of y is that it allows us to talk about f.
If we have an equation relating X to Y then that's a relationship between rwo nimbers.
For example if you have that y=
[tex]y = {x}^{3} [/tex]
...then that means that X and Y are some numbers obeying that equation
