Which function has a vertex at (2, -9)?
O f(x) = (x – 3)2
O f(x) = (x + 8)2
O f(x) = (x – 5)(x + 1)
O f(x) = -(x - 1)(x - 5)

What are the options

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
