After plotting the data where x represents the length of the side of a polygon, and f(x) represents the area of the polygon, Jack used technology and constructed an appropriate model to approximate the area of the polygon. Use the model Jack created to predict the area of a polygon that has a side length of 3. f(x) = x2 + 3x + 1 18 20 19

Find the value for a which maximizes the area of the rectangle. The rectangle has one side om the x-axis and two vertices on the curve y=27-x2.

A rectangular dock that measures 12 feet by 16 feet is treated with auniform strip of nonslip coating along both sides and both ends. How wide isthe strip if one-half of the dock is treated? If we let x represent the width of thestrip, then we can use the equation (16 -2x)(12 - 2x) = 1/2(12)(16) to determinethat the width of the strip is 2 feet. I've been doing well with polynomials I just do not understand visually what "treated along both ends and sides" mean. What is the end of a rectangle? Also, I do not understand the 2 in '2x' (2 times the width of the strip) why is that added? I guess I am more concerned about how the equation actually maps to the real world scenario.
