The volume of gas a balloon can hold varies directly as the cube of its radius. imagine a balloon with a radius of 3 inches can hold 81 cubic inches of gas. how many cubic inches of gas must be released to reduce the radius down to 2 inches?

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

What is the inverse of the function f(x) = 2x + 1?
