P = 4V^2 + E^4V +3

The area under a pressure-volume curve for a gas gives the work done by the gas when expanding or contracting.

i) Draw a sketch of the pressure-volume curve for positive values of volume.

ii) Mark the work done from 1m^3 to 3m^3

iii) Find the work done by the gas when expanding from 1m3 to 3m3 by performing a definite integral.

I am unsure how to do these questions. Any help will be appreciated, thanks.
