Question

How do you find the domain and range of `f(x) = |x - 2|`?

Answer 1

Domain : `All` `Real` `Numbers`
Range : `y >=0`

Explanation:

We notice that there is no limitations for `x`, so the domain is `All` `Real` `Numbers`. We now need to find what `y` can be, but because `x` can be any real number, that means that `y` can be any number that's isn't negative. So the range is `y >=0`.
