Question

(20 Points)

y = 4(x + 6)2 + 2
O y = -4x² + 48x + 136
O y = 4x2 + 48x + 146
O y = x² - 48x + 146
O y = -14x2 – 48x – 146

Answer 1

2nd option will be the answer (y=4x²+48x+146)

Explanation:

y=4(x+6)²+2

y=4(x²+2*x*6+6²)+2 [(a+b)²=a²+2ab+b²]

y=4(x²+12x+36)+2

y=4(x²)+4(12x)+4(36)+2

y=4x²+48x+144+2

y=4x²+48x+146
