Answer:

The output (y-value) when x = 2

Step-by-step explanation:

You have a function y = f(x).

Then f(2) means that you substitute x = 2 into f(x) to work out the output y.

Hope this helps!

The original notation is f(x). This is another way of saying y. If you plug 2 into x, you will get your y. The answer would be the second choice: the output (y-value) when x=2.
