An open box is formed by cutting a 5 inch square measured from each corner and folding up the sides. if the volume of the carton is then 40 in3, what was the length of a side of the original square of cardboard?

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

there are no choices to this, can you give us some choices so that i can answer it
