Question

How do you find domain and range for `f(x) = abs(x-2)`?

Answer 1

The domain is the set of real numbers `D(f)=R` and the range is
`R(f)=[0,+oo)`

Answer 2

What is the graph look like?graph{|x-2| [-3, 7, -5, 5]}

Explanation:

1. Domain
   Look at the x-axis, where can't x be. In this case x can be every real number, `(-oo,oo)`.

2. Range
   Now, look at the y-axis, where can't y be. In this class, y can't be negative, `(0,oo)`.
