Answer:
y = x for x ≥ 0 and y = - x for x < 0
Step-by-step explanation:
The absolute value function is written as y = |x| and it is defined as following
|x| = x when, x ≥ 0 and |x| = - x when, x < 0.
Therefore, the equations for the domain of x ≥ 0 is y = x
and the equation for the domain of x < 0 is y = - x (Answer)
