f(x) = 5

g(x) = $\sqrt{x + 2}$

(f-g)(x) = 5 - $\sqrt{x + 2}$

(f * g)(x) = 5 $(\sqrt{x + 2})$ = $5\sqrt{x + 2}$

(f/g)(x) = $\frac{5}{\sqrt{x + 2}}$ = $\frac{5\sqrt{x + 2}}{{x + 2}}$

f(g(x)) = 5

Step 1. Solve the equation for x
Step 2. Find the intersection
Step 3. Find the union -> x = - 8/3
Step 4. The equation has 2 solutions
x1 = -8/3
x2= 16/3
