(a)
Write a polynomial function
Given:
Length is 4 times the width and height is 2 times the width.
The cooler has insulation that is 1 inch thick on each of the four sides and 2 inches thick on the top and bottom.
Calculation:
Let the width of the cooler is
Therefore, length is
Hence, the polynomial function
