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
