Question

If f(x) = x − 4, what does f(3) represent?

The value of (x − 4) when x = 3

The value of x when (x − 4) = 3

The value of 3f(x) when x = 3

The value of f(x) when (x − 4) = 3

Answer 1

If f(x) = x − 4, what does f(3) ,
then
f(3) = 3 - 4.

We need substitute x by 3.
So, the answer is A. The value of (x − 4) when x = 3
