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

Apr 6, 2017

Domain: $x \in \mathbb{R}$
Range: $f \left(x\right) \ge - 4$
Domain: Any real value i.e $x \in \mathbb{R}$
Range: Any real value greater or equal to $4$ i.e $f \left(x\right) \ge - 4$ since minimum value of |x| is $0 \therefore f \left(x\right) \ge - 4$ graph{|x| -4 [-12.66, 12.65, -6.33, 6.33]} [Ans]
