Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

This is my first time posting on this site. I'm doing Calculus 2 and am stuck on finding whether or not the following functions are invertible in the given intervals and explaining why.

(a) sechx on [0,infinity)

--> I solved (a) but (b) and (c) is where I'm stuck.

(b) cos(lnx) on (0, e^pi)

(c) e^(x^2)

Can someone please help?
