Answer 1

Answer:

x = 8

Step-by-step explanation:

f(x) = $\sqrt{3x}$

g(x) = $\frac{1}{x+3}$

(f o g)(x) = f[g(x)]

             = $\sqrt{\frac{3}{x+3} }$

This function is defined for (x + 3) > 0

(x + 3) - 3 > 0 - 3

x > -3

From the given options x = 8 is the only solution which is greater than -3.

Therefore, x - 8 is in the domain of the given function.
