The function  represents a reflection of
 represents a reflection of  across the y-axis ⇒ 3rd answer
 across the y-axis ⇒ 3rd answer
Step-by-step explanation:
Let us revise the reflection across the axes
- If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x)
- If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)
∵ 
∵ g(x) is the image of f(x) after reflection across the y-axis
- From the rule above reflection across the y-axis changes the sign of x
∴ 
∵ 
∵ 
∴ 
∴ 
The function  represents a reflection of

It’s B 
If y-x=6
 Y +X =_10 
then y= 6 + x, instead of y insert this no 
6+ x+ x =-10
6 + 2x =-10 then collect like terms 
2x =-10-6
2x=-16 then multiple both side by 1/2
X=-8 
Y=6+x instead of x insert -8
Y=6-8
=-2
