# Thread: What is the domain and range of this function?

1. ## What is the domain and range of this function?

What are the domain and range of the function f(x) = -4 - sqrt(9 - x^2)? a.)Domain(-3,0),Range(0,4) b.)Domain(-3,3),Range(-7,-4) c.)Domain(-inf,inf),Range(-inf,inf) d.)Domain (-1, 1), Range (-inf, inf)

2. Domain(-3,3),Range(-7,-4)

3. Thank you so much Amer!

4. This should be easy to answer if you consider for which x values that $\sqrt{9 - x^2}$ is defined.
