I'm having trouble finding the sums of functions.
My particular problem is,
f(x)=radical(x2-4) ; g(x)=x2/x2+1
They're asking me to solve (f+g)(x).
If (f+g)(x) is the same thing as f(x)+g(x) then:
Can x2/x2+1 be simplified so I can add the two functions easier?
I tried simplifying a bunch of things but I can't seem to get anywhere.
Any help would be appreciated. Thanks in advance!
