Question #3fe19

Answer 1

Undefined

Explanation:

When we see an `F(x)` we know this is a function. Now what a function?

A function is simply an equation that has an input and a related output.

Lets say for a second that `F(x) = x^2`
This is saying that if I put in some number `(x)` I will get out a new number, `F(x)`

I would also like to point out that `F(x)` is the same as writing `y`. The only difference is that `F(x)` is used exclusively for functions.

Ok, lets go back to the equation `F(x) = x^2`
Lets try to find `F(2)` of that equation

Well, to do this we just plug in `2` for the `x` in the equation!
`F(x) = 2^2`
`F(x) = 4`

Thats all there is to it!
Lets try doing `F(4)` this time.
`F(x) = 4^2`
`F(x) = 16`

Although functions can get much more difficult, that is the general idea of a function! Hope this helps!
