Answer:
The graph is constant from (-oo,-2)U(4,oo).
The graph is increasing from (-2,4).
The graph never decreases.
Explanation:
Take the x values from when the line is constant (not rising or falling), increasing (rising), and decreasing (falling).
oo means infinity
The graph is constant from (-oo,-2)U(4,oo).
The graph is increasing from (-2,4).
The graph never decreases.
