Maxima minima

[phymatter]

Main Question or Discussion Point

what is the reason that the minima and maxima of ( e^x2 -1 )^1/2 and ( e^x2 -1 ) are the same ??

How do you find the max and min of a function?

hi phymatter!

this has nothing to do with calculus …

if g is a monotone increasing function, then the maxima and minima (and the local maxima and minima) of g(f(x)) and f(x) will be the same …

now prove it! ​
