Question

If f(x)=3x if x<0, x+1 if 0≤ x≤ 2, and (x-2)^2 if x>2, how do you find f(2)?

Answer 1

`f(2)=3.`

Explanation:

To find `f(2),` we have to see, in the Defn. of `f,` where `x=2` is

permissible.

We find, this permissible at : `f(x)=x+1, if 0 le x le 2.`

Therefore, we plug in `x=2` in `f(x)=x+1,` and, get,

`f(2)=2+1=3.`
