Answer:
Domain: All real numbers, -∞ < x < ∞
Range: Everything equal to and above y ≥ -8
Explanation:
I have attached a graph of this function below. The domain is all possible x-values of the function (the inputs) and the range is all possible y-values (the outputs) of the function. I will be writing these with inequalities since it is not specified in the question.
Here, the domain is all real numbers. This is because the function's x-values go from -∞ to ∞, it never stops. This can be written as -∞ < x < ∞.
We see a point at (-2, -8) and that the graph is all above this point. This gives us a range of y ≥ -8.
