[tex] \int_{-\infty}^{\infty} e^{-|x|} dx [/tex](adsbygoogle = window.adsbygoogle || []).push({});

Could someone tell me why this integral, when you split it comes out to be:

[tex] \int_{-\infty}^0 e^x dx + \int_0^{\infty} e^{-x} dx [/tex]

I keep thinking it should be e^(-x) in the first integral. I don't know why its positive. I can solve this integral otherwise. Thanks again.
