When a problem asks for f(5), what is it asking for? a. the value of f(x) when x = 5 b. the value of x when f(x) = 5 c. the product of f(x) and 5 d. the fifth letter of the alphabet

Here we have this function f(5)

Suppose the original function was f(x).

Now if we have to find the value of the function f(x) when we are given x=5, then we replace the x by 5.

So the function becomes f(5) at x=5.

For example:

If we have a function,

and we are to find value of this function at x=2,

then we replace the x by 2 everywhere in the function,

So this is how it works.

When a problem asks for f(5), it is asking for value of the function f(x) when x=5. Option A. is correct choice.
