4. The area of a rectangle is 32x^11 y^7 square yards. If the length of the rectangle is 8x^4 y^2 yards, which expression represents the width of the rectangle in yards?
256x^15 y^9
4x^7 y^5
24x^15 y^9
24x^7 y^5

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
