Answer:
y= -x+4 if x<0
y= x+4 if x≥0
Step-by-step explanation:
When writing a piece-wise function, we simply look at the portion of the graph that covers the given domain and derive an equation.
When looking at the part of the graph when x<0, we can derive the equation:
y= -x+4.
For x-values greater than 0, we can get:
y= x+4.
