Which of the following is an example of function notation?

Question

A. Volume + radius = 67
B. Volume/radius = 67
C. Volume x radius = 67
D. Volume(radius) = 67

Answer 1

well the function f is usually written in the form

f(x) = 2x-2

so D looks like the choice intended.

But saying Volume(radius) = 67 is a bit strange, since it implies that no matter which value "radius" has, the Volume remains constant at 67.

If the value of Volume is 67 when the radius is 3, then one would write Volume(3) = 67.
