Question

After plotting the data where x=the side of a polygon, and f(x) = the area of the polygon, Jack used technology and

determined the appropriate model to approximate the area of the polygon, F(x) = x^2 + 3x + 2. Use the model Jack
created to predict the area of a polygon that has a side length of 3.

Answer 1

Answer: 19

Explanation:

As per the model created by Jack; f(x) determines the area and x represents length so f(3) = 9+9+1

Therefore, f(3) = 19
