Question

What does the notation f(2) mean?

O multiply fby 2
o the output (y-value) when x = 2
o the value of x when the output is 2
DONE

Answer 1

The output (y-value) when x = 2

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!

Answer 2

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.
