#### Answer:

Domain;

Range;

#### Explanation:

The domain for this function can be considered by considering what values of x make y be defined, and we see evidently that

The range can be found by considering the graph of this equation, just

graph{x^2+3 [-18.67, 21.33, -1.08, 18.92]}

So from this we see that

hence

Hence yielding a range of;
