The cross section of a wooden storage structure can be modeled by the polynomial function -3/80(2x-40)(2x+40) where x and y are measured in feet, and the center of the structure is where x 5 0. a. Explain how to use the algebraic model to find the width of the structure. b. Use the model to find the structure's width. Show your work c. Use the model to find the coordinates of the center of the structure. Show your work.
