Answer:
A
Step-by-step explanation:
-When the function moves to the right or left to the x axis, the number has to be in "( )"
-If it moves to the right, you SUBTRACT the amount of units
-It it moves to the left, you ADD the amount of units.
So in this case, it is moving to the right 12 units so it is 
Answer:
B.
Step-by-step explanation:
Vertex with (2,4) means that the equation will have:
y=a(x-2)^2 + 4
Open downwards means that the a will be negative:
so: y = -a (x-2)^2 + 4
Stretched by a factor of 3 means that the a=3
So if we combine all of these, we will get the equation:
y = -3 (x-2)^2 + 4
