Question

f(x)=x-1/x squared+1
g(x)=x+10/x+13

what is (f o g)(x)?

Answer 1

\[\frac{x-1}{x^2-1}\]?

Answer 2

or maybe
\[\frac{x-1}{x^2+1}\]?

Answer 3

and
\[g(x)=\frac{x+10}{x+13}\]

Answer 4

nope

Answer 5

if so then
\[f\circ g(x)= f(g(x)=f(\frac{x+10}{x+13})\]
\[=\frac{\frac{x+10}{x+13}-1}{\frac{x+10}{x+13}+1}\]

Answer 6

not that either
