Question 38251
PLEASE ONLY PUT one QUESTION IN EACH SUBMISSION!!!

I will solve the first one, then try the rest on your own, if you have queries after that e-mail them AND your work to me at alexusbandona@yahoo.com

find (f . g)(x) and (g . f)(x) for each function
{{{f(x)=-6x+9}}}, {{{g(x)=5x+7}}}
if for f {{{x= 5x+7}}} then:
{{{f(5x+7)=-6(5x+7)+9}}}
{{{f(5x+7)=-30x-42+9}}}
{{{f(5x+7)=-30x-33}}}

Hope this helps and feel free to contact me with further questions,
