Would someone please help me see how to work out the problem f/g, when f(x) = square root of 3x, and g(x) = square root of x^21 please? and I need to figure out the domain. Thank you

Best ResponseYou've already chosen the best response.0first of all g(x) must be not equal to zero,and sqrt must not be negative value as then sqrt will be undefined..therefore work out the the in equality x^21>0 whis is modified as (x1)(x+1)>0.
