This graph is that of a parabola, which in turn represents a quadratic (2nd order) equation, also a polynomial. The domain of any and all polynomial(s) is "the set of all real numbers," or (-infinity, infinity).
Volume of a sphere is given by the formula:

If we pull the 4 out front we have,

.
Volume of a cone is given by the formula:

Notice that if the height of the cone is equal to the radius,

then it's exactly what we see in our volume formula without the 4!
All you need to do is multiply 18*60 = 1080 feet per minute, which is really fast.
Answer:
Neither
Step-by-step explanation:
This is a linear function as opposed to an exponential function as there are no x terms in higher powers.
