Answer A-C (refer to picture for graphs. A.) Using a graphing utility to graph S(x). All four graphs use a viewing window with limits of 0
B.) Using a graphing utility determine the minimum amount of material that can be used to construct the box.

“The minimum amount of material is about ___ square inches.”

C.) What are the dimensions of the box that minimize the surface area?

“The value of x that minimizes the surface area is ___ inches”

“The value of y that minimizes the surface area is ___ inches.”

Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x h(g(f( = x2+ vx+ x + y
