Answer: down there
Step-by-step explanation:
When solving a radical equation, it is important to always check your answer by substituting the value back into the original equation. If you get a true statement, then that value is a solution; if you get a false statement, then that value is not a solution.
Answer:
third option: (x+3) / √x+2
Step-by-step explanation:
f(x) = √x+2 g(x) = (x² + 1) / x
(g·f)(x) = g(f(x)) = ((√x+2)² + 1) / √x+2
==> (x+2+1) / √x+2
==> (x+3) / √x+2
The discriminant determines the number of real solutions. If the discriminant is positive, there will be two solutions. If it's negative, there are no solutions. If it's 0, there is one solution
