Answer:
${x|x>=-4}; {y|y>=2}$
Step-by-step explanation:
We see that the left-most point on the function is $(-4, 2)$. As there is an arrow on the very right of the function, this means the function's domain is ${x|x>=-4}$, meaning $x$ is always greater than $-4$.
We see that the bottom-most point on the function is $(-4, 2)$(coincidence that they are the same point, won't always be like this). As there is an arrow on the very right of the function, and the function is increasing all the time, this means the function's domain is ${y|y>=2}$, meaning $y$ is always greater than $2$.
Putting these together, we see that the domain and range of the function shown is ${x|x>=-4}; {y|y>=2}$
