SOLUTION: Find f*g for f(x)= square root x+7 ; g(x)= 2/x and state the domain. Dont solve it as a composite function just multiply. I got (-infinity,0)U(o,infinity) but i have no idea how

Question 471518: Find f*g for f(x)= square root x+7 ; g(x)= 2/x and state the domain. Dont solve it as a composite function just multiply.
I got (-infinity,0)U(o,infinity) but i have no idea how i got it or if its even correct. Thank you
