# How do you find the domain and range of # -x^2+7#?

##### 1 Answer

Domain:

Range:

#### Explanation:

The domain is the set of all possible

Let's start by taking a look at the graph

The domain of

graph{x^2 [-10.54, 9.46, -0.56, 9.44]}

Domain:

Range:

Now let's look at the graph of

graph{-x^2 [-10.17, 9.83, -9.48, 0.52]}

Domain:

Range:

Lastly, let's look at the graph for the function given:

graph{-x^2+7 [-9.88, 10.12, -2.72, 7.28]}

Domain:

Range:

The domain is still unchanged but the range is
