A cube shaped box has an edge of x cm.
 
a) Write an expression for the function $L(x)$ that gives the length of tape used to run a layer of tape around all the edges.
        $L(x) =$
 
b) Which (if any) of the statements best explains what would happen if your roll of tape contained $L(x) - 6$ cm of tape?     Select You would have 6 cm less than the amount of tape needed to cover the edges of a box whose edges are length x cm. You would only have enough tape to cover the edges of a box whose edges are 6 cm less than a box with edges length x cm. You would have enough tape to cover all but 6 of the edges of a box whose edges are length x cm. You would have 6 cm of tape left over after covering the edges of a box which has edges length x cm. None of the above
 
c) Which (if any) of the statements best explains what would happen if your roll of tape contained $L(x-6)$ cm of tape?     Select You would have 6 cm less than the amount of tape needed to cover the edges of a box whose edges are length x cm. You would only have enough tape to cover the edges of a box whose edges are 6 cm less than a box with edges length x cm. You would have enough tape to cover all but 6 of the edges of a box whose edges are length x cm. You would have 6 cm of tape left over after covering the edges of a box which has edges length x cm. None of the above
 
d) If the tape must be wrapped beyond each corner for a distance of 3 cm, express the length of tape used in terms of a shift of the function $L$. Your answer must be entered using a horizontal and/or vertical shift of the funtion $L(x)$, do NOT give an explicit formula.
