Fernando Mcdonald · Answer 1

V (x) = the volume of water, in³, as a function of the height, x, in.

Therefore by definition,

V⁻¹ (x) represents the height as a function of volume.

The expression V⁻¹ (20) represents the height of the water in inches when the volume is 20 cubic inches.

Answer: 4)

The height of the water n the tank, in inches, when the volume is 20 cubic inches.
