After plotting the data where x equals the length of the side of a polygon, and f(x) represents the area of the polygon, Jack used technology and determined the appropriate model to approximate the area of the polygon, f(x) = x2 + 2x + 3. Use the model Jack created to predict the area of a polygon that has a side length of 3.
We are given the model to approximate the are of the polygon to be f(x) = x² + 2x + 3 where x is the length of the side For a polygon with a side length of 3, x = 3 f(3) = 3² + 2(3) + 3 f(3) = 18 The area is 18
