Answer:The answer is (C) Y = 3x² – 24x + 18

Step-by-step explanation:Y = 3(x-4)² – 22

First step is to simplify (x-4)²

⇒ Y= 3(x-4)(x-4)-22

⇒ Y= 3(x²- 4x – 4x + 16) – 22 = 3(x² – 8x + 16) – 22

Next step is to open the parenthesis

⇒ Y = 3x² – 24x + 48 – 22

The final step is to collect like terms and simplify the equation

⇒ Y = 3x² – 24x + 26
