Question

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

Answer 1

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 2

The `function` is `(x-4)`.
f(3) represents the value of the `function` when `x = 3`.

Answer 3

so the first choice? :L

Answer 4

Hopefully that helps you to make the connection to the correct answer D:
I can make it a little bit more explicit if needed.

\[\Large f(\color{#DD4747}{x})\quad=\quad (\color{#DD4747}{x}-4)\]\[\Large f(\color{#DD4747}{3})\quad=\quad (\color{#DD4747}{3}-4)\]

So here we can see that f(3) represents the solution to (x-4) when we plug x=3 in.

Answer 5

Yesss good good good :D

Answer 6

yay!
