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

Well, from where to where do this mappings go? Are they supposed to map from the real numbers into the real numbers?

In addition, I suppose by square root you only mean the positive root? Else those aren't functions

first 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.

that's not true. what if x > 3? Then we have a square root of a negative number.
