Use f(x) = 1/2 and f^-1(x) = 2x to solve the problems.

f(2)=
f^-1(1) =
f^-1(X2)) =

1 is c

2 is a

3 is a

step-by-step explanation:

78.59 is the mean

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

i think the correct option is the second option.
