After plotting the data where x represents the length of the side of a polygon, and f(x) represents the area of the polygon, Jac
k used technology and determined the appropriate model to approximate the area of the polygon, f(x) = x2 + 2x + 5. Use the model Jack created to predict the area of a polygon that has a side length of 3. 10 18 19 20

<u>Answer-</u>
<u>Solution-</u>
The total money that you have or maximum amount that you can spend = $20
Let's assume,
x = Number of tomatoes bought
y = Number of red peppers bought
Price of tomatoes per pound = $2.50
Price of red peppers per pound = $4
Hence,
Total cost of tomatoes = $2.5x
Total cost of red peppers = $4y
As you can spend at most (any amount less than or equal to) $20, so
Taking a point as origin (0, 0) and then putting it in the equation,
As this satisfies, so the shaded region will be towards that point i.e origin
From the graph, the two solutions that are on the boundary line are (8, 0), (5, 0)
