Your original commented question:
Did some checking. Reflection seems to be defined two ways for functions.
If F1(x)=F2(-x) or F1(x)=-F2(x) then F1 reflects F2 in one or other axis.
Clearly this is not the case for Functions 1 and 2, so you're right, under this definition Function does not reflect Function 2. Everything depends on how reflection is defined.
Now let's see your new question.
I think the answer is D. The coefficient 2 makes Function 2 steeper. By the above definition of reflection, the functions do not reflect each other.
