could someone help me and explain what i need to do ? I'm not sure on how to do this. The amount of cloth used to make four curtains is given by the function A = -4x² + 40x, where x is the width of a curtain in feet and A is the total area of material in square feet. 1) Determine width of the curtain given the total area of the curtain is 96ft². 2) Determine the area of the curtain given a width of 3.5 feet. 3) Graph the function and label the axis of symmetry, vertex, and the roots (solutions). 4) When the curtain is 5ft width, will 60ft² material be enough? .
