Answer: The answer is (c)
Step-by-step explanation: Given that there are two functions f and g, defined by
We are to find f*g and also its domain.
Also, its domain will be all real numbers, since the function f*g is defined at all 'x' in real numbers.
Thus, the correct option is
$=\sqrt{4^2}\times\sqrt{2^2\cdot3}$
$=4\times2\sqrt3=8\sqrt3$
