Question 979157
Those look like multiplication of functions, not function composition.


Using #2 as example,

{{{g(x)f(x)=(8/x)(x+7)}}}
{{{8(x+7)/x}}}, and this is the best way to show this product function, because this should be undefined for x at 0.


I do not understand quite what you are showing for #1.  multiplying g and f is the same as multiplying f by g.
