The formula for the volume of a sphere is a power function: V(r) = 4/3 * Pi* r^3

What is the domain of the function in this situation?

All real numbers
r>=0
r<=0
What is the range of the function in this situation?
All real numbers
V(r)>=0
V(r)<=0

r≥0

V(r) ≥0

Step-by-step explanation:

V(r) = 4/3 * Pi* r^3

The domain is the input values for r

The radius cannot be less than 0  but can be any number bigger than 0

What is the domain of the function in this situation?

r≥0

The range is the output values for the function or the volume

The volume must be greater than or equal to zero

V(r) ≥0
