Let the intial cost = x




Check the picture below.
the quadrilateral is a parallelogram, thus the diagonals bisect each other, so, we could have used either diagonal, and get the same midpoint.
I am going to assume this is for calculus. You would need to find the derivative of each because derivative represents rate of change.
The derivates are:
y'=1
y'=3
y'=4
y'=2
Therefore the answer it the third choice because it has the largest derivative<span />
