Question 30449: I'm not sure if I am posting this in the right area. But I need to:
For the indicated functions f and g, find the functions f+g,fg,fg, and f/g and find their domains.
f(x)=3x g(x)=x^2+4
Could you show me how this is done. I did it using word and cannot paste the answer in here and need something to check my work by.
Thank you so much!

Question 30468: First, I'm told that X can be read as 1*X where the 1 is not written because it is "understood" and when X=9, x= 1* +9 or 9. It would also follow that if X=9 then X=1*9 or +9.
I'm also told that a negetive number times a negetive number yeilds a positive answer. I know that 6^2=36 so it makes sense that
6^2 would mean 6*6 or +36.
My problem is that when I enter 6^2 into my graphing calculator, I get 36. When I enter it into my scientific calculator I get +36. A teacher explained that I should read 6 like I read X, as 1*+6^2= 36. Another teacher explained that 6^2 means (6)*(6)and that the answer is infact +36. Which teacher and which calculator is right?
