Hey can you me posted picture of question

For this case we have the following equation:
 y = 4 (x-2) ^ 2-1
 Rewriting we have:
 y = 4 (x ^ 2-4x + 4) ^ 2-1
 Multiplying the common factor 2 we have:
 y = 4x ^ 2-16x + 16-1
 Adding the constant term we have:
 y = 4x ^ 2-16x + 15
 
 y = 4x ^ 2-16x + 15
 option D

Not sure what the question is?
