Clearly when x is bigger than one the term -x^38 will dominate the result.
When absolute value of x grows, x^38 becomes a larger positive number and - x^38 a larger negative number. Then both ends of the function tend to negative infinity.
The other diagonal would be 13 feet as well because it is a rectangle.
