The document describes a math question from an exam where a teacher adjusted students' scores using a polynomial function f of degree less than 3. The function was required to keep scores of 0 and 10 unchanged, and change a score of 5 to 6. The polynomial that satisfies these requirements is y= -x^2/25 + 7x/5. This is demonstrated by substituting the given values of 0, 5, and 10 into the response options and determining which one outputs the correct results.
