K exp(-|f|) for -4<f<4 and zero otherwise.

Kindly find value of K

It's an even function, so you don't need two integrals.

$\displaystyle .5=k\int_0^4e^{-x}dx=k\bigl(1-e^{-4}\bigr)$ - Oct 11th 2009, 10:13 PMmoonnightingalei think it should be other way round
Thanks a lot

i think it should be like this

0.5 = K [exp(-4) -1]
