Question

What is the domain and range for;
ƒ(x)= -√25-x^2

Answer 1

y=-x^2 -5

Domain is all real numbers

Range is y<-5

Explanation:

1) -5 means the min/max is at that y.

2) for a parabola, Domain is always all real numbers.

3) due to the graph being flipped with the negative, you now have a maximum value, giving the range of y<-5.

4) enjoy the answer.
