A polynomial where the ends are facing downwards is an even-degree polynomial with a negative leading coefficient.
An example for this is : f(x) = -x^2
where the degree is even (2) and the leading coefficient is negative (-1).
When graphing this function, you'll find both ends pointing downwards.
235-(-12)=247; his elevation changed by 247 m.
