A can of sardines is made to move along an x axis from x1 = 0.2 m to x2 = 1.2 m by a force given by F = iF0exp(0.4x), with x in meters and F0 = 4.5 N. (Here exp is the exponential function.) How much work is done on the can by the force?

Work is the integral of force x distance.
In this case,
1.2
W = (Integral)4.5 exp(0.4x)dx
0.2
= 4.5/(0.4)[exp(0.4*1.2)  exp(0.4*0.2)]

Ok, so according to this W = 36.97 J
This, however, is the wrong answer. Did I do something wrong in my calculations???
