How about
3/2 * {1 - exp (-4)} = 1.4725...

Int(3*e^(-2x))
= 3 *(e^(-2x)/-2
= -3/2*(e^(-2x))
result between limits
= 3/2(e^0-e^-4)
=3/2(1-1/e^4)

∫3/e^(2*x) = -3*(2 *e^(2*x))
- 3 ( 2 * e ^(2*0)) - [ - 3 ( 2 * e ^(2*2)) ] = 3/2(1-1/e^4)
Good Luck.

DutchProf is right (everyone else is wrong):
3/2 * {1 - exp (-4)} = 1.4725...

int. (0,2) e^(-2x) dx
= e^(-2x)/(-2) between 0,2
=-1/2 [e^(-4) - e^(0)]
=-1/2 [e^(-4)-1)
