Question

How do you find the domain and range of `f(x) = |x| - 4`?

Answer 1

Domain: `x in RR`
Range: `f(x) >= -4`

Explanation:

Domain: Any real value i.e `x in RR`

Range: Any real value greater or equal to `4` i.e `f(x) >= -4` since minimum value of |x| is `0 :. f(x) >= -4` graph{|x| -4 [-12.66, 12.65, -6.33, 6.33]} [Ans]
