Answer:
B
Step-by-step explanation:
A Piecewise function, is a function whose main feature is to be defined by a sequence of intervals. In these graphs we have:
So we have three intervals
x=2, for y=0
x >2, for y=3
x ≤ -3, for y=-4
The Piecewise function is putting together these intervals in the coordinate plane. So, it's B.

we have the inequality
step 1
Find out the first solution (positive case)
The first solution is all real numbers less than or equal to 1.20
Interval (-infinite,1.20]
step 2
Find out the second solution (negative case)
Multiply by -1 both sides
The second solution is all real numbers greater than or equal to -2.8
the interval [-2.8, infinite)
step 3
Find out the solution to the given inequality
The solution is
[-2.8, infinite) ∩ (-infinite,1.20]=[-2.8,1.20]
the solution is the interval [-2.8,1.20]
