Dude its

-10<x<0

0<x<4

4<x<8

Explanation:

You missed to add the graph. I possibly found and attached the complete graph question below.

From the attached graph,

Given the portion of piecewise function


f(x) = -2

has the domain
-10<x<0.

In other words, the graph of this portion is showing discontinuty or hole occurs at x = 0 and x = -10. Therefore, It does not include x = 0 and x = -10.

  • A discontinuity occurs when a gap or hole appears in the graph.

Similarly, the portion of piecewise function


y = 2x+1

has the domain
0<x<4.

As the graph of this portion is showing discontinuty or hole occurs at x = 0 and x = -4. Therefore, the domain does not include x = 0 and x = -4.

And the 3rd the portion of piecewise function


f\left(x\right)=-(1)/(2)x

has the domain
4<x<8.

As the graph of this portion is showing discontinuty or hole occurs at x = 4 and x = 8. Therefore, the domain does not include x = 4 and x = 8.
