Given $f(x)=2x-6$ and $g(x)=x+3$, sketch the graph of $f(x), g(x), (fcirc g)(x)$, and $(gcirc f)(x)$
$begingroup$
This is what I got:
Blue: $g(x)$
Red: $f(x)$
Yellow: $(gcirc f)(x)$
Green: $(fcirc g)(x)$

If $*$ was composition it would be correct, but as product the last two are wrong.

Well product is commutative, so that immediately throws up a flag that something's amiss.
