Explanation:

Step1: Identify domain from graph

The function has a closed dot at $x=-2$ (included) and an open dot at $x=1$ (not included). All $x$-values between these are covered.
Domain: $-2 \leq x < 1$

Step2: Identify range from graph

The lowest $y$-value is $0$ (at $x=-2$, closed dot) and the highest $y$-value is $4$ (at $x=0$). All $y$-values between these are covered.
Range: $0 \leq y \leq 4$

Answer:

Domain: $\boldsymbol{-2 \leq x < 1}$
Range: $\boldsymbol{0 \leq y \leq 4}$
