First you should subtract 18 and 2. Then divide 24 by 3. Finally calculate the difference. The answer would be 15 over 2 or 7.5
Answer B go=x3 - 3 is the correct answer
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)
