Answer:
Domain: All real numbers or (-∞, ∞)
Range: [-9, ∞)
Explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted by the domain.
We can see that you can plug in any x-value into the graph. Therefore, any number would work (All real numbers).
We can also see that are absolute minimum y-value is -9. Therefore, our range is from -9 (included) to infinity.
