Okay
The graphs show the force Fi (in pounds) required to move an object 9 feet along the x-axis. Order the force functions from the one that yields the least work to the one that yields the most work without doing any calculations. Explain your reasoning.

Give me some hints, please? I don't know anything about physics, but I think this is from a physics section of problems in my textbook.

EDIT: I made a booboo with the title, sorry.

this is indeed a physics problem, the work done is equal to the area under the curve.... i think

Yeah, I'm pretty sure Area = Work, since they're both equal to distance times force.

$\displaystyle W = \int_{x_0}^{x_f} F(x) \, dx$
