You need its anti derivative and the derivative of e^(1.4x) is 1.4e^(1.4x). You get that from the chain rule by first taking the derivative of the outer function, which is e^x, and multiplying it by the derivative of the inner function which is 1.4x. So toget44e^(1.4x) you need to differentiate (44/1.4)e^(1.4x) so that is the integral along with the usual arbitrary constant added on.
