Step-by-step explanation:
To reflect a graph, f(x) over the x-axis, you take -f(x). So if f(x)=x^2, then -f(x) is -x^2. Then g(x)=-x^2 is the reflection of your function f(x) over the x-axis.
 
        
                    
             
        
        
        
Answer: 
Step-by-step explanation:
 For this exercise it is important to remember the following:
 
 Given the following expression:
 
 You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:
 1. Replace  with
 with  and simplify:
 and simplify:
 
 2. Descompose 12 into its prime factors:
 
 3. Substitute into the expression:
 
 4. Since ![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da) , you can simplify it:
, you can simplify it:
 
 
        
             
        
        
        
Answer:
Answer would be 9y+36
