Let $f:X \rightarrow Y$ and $g:Y\rightarrow Z$
Then one defines composition of functions as follows, $$g(f(s)):X\rightarrow Z $$ For all $s\in X$. I also saw the following notation being used, $$g \circ f:X\rightarrow Z$$ Now I was wondering how to say $g\circ f$ while speaking?
Can it be pronounced "$g$ circle $f$" or should it be pronounced as "$g$ compose $f$"?
I also think there are couple of mistakes in my understanding then i request to let me know.
