If f(x) = square root x and g(x) = |x|, find fg, f/g and their domains.

I'm not sure even how to start this problem. If you could point me in the right direction, I would appreciate it.

The place to start would be with the definition of the notation.

What does 'fg' mean? f(x)*g(x)?

 

[bubblefiz]

fg= f(x)(g(x) = ( √x) (|x|)

F/g = f(X)/g(x) = √x/ |x|


for domains:

All real numbers

Df/g {x|x>0}
g(x) can not = 0
