Answer:
 

Step-by-step explanation:
The parent function is 

First it is asked to reflect over the y axis so using the rule 

Our function looks like 

Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule

When subtracting a 7 it looks like now 
 where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule 

where a is the vertical stretch. So now it would look like

 
        
             
        
        
        
SR because any point on a perpendicular bisecting line is equidistant from the ends of the bisected segment.
