x^2 in the function that you typed is x * x ( x multiplied by x). It represents a second degree because there are only 2 "x"s multiplied together. If there were 3 "x"s multiplied together, we would have x^3. Since the highest exponent in this function is 2 (in x^2), we call this function a 2nd degree polynomial.
The answer to your question is the last option because the total of the whole table is 1.0. And, mathematically speaking, y cannot possibly be 1.0 if the tables values all add up to 1.0
