Evaluate the following definite integrals int_{2}^{4}e ^{-2x}dx

OpenStudy (anonymous):

\[\int\limits_{2}^{4}e ^{-2x}dx\]

OpenStudy (anonymous):

F'(4)-F'(2)....n the integral of tht is -2e^(-2x)

OpenStudy (anonymous):

The integral is actually (-1/2)e^(-2x), evaluated from 2 to 4 gives (-1/2)(e^-8-e^-4)
