Give an example of a pair of functions f: B -> C and g: A -> B such that f(g(x)):A -> C ........?

is onto, but g is not onto ?

Give an example of a pair of functions f: B -%26gt; C and g: A -%26gt; B such that f(g(x)):A -%26gt; C ........?
f:x:-%26gt;3x-3, g:x-%26gt;4x+4.


f(g(x))=fg(x)=3(4x+4)-3
