Here you haven't provided any function, so I'll assume this one:
This is a quadratic function whose graph represents a parabola. Any parabola has its vertex at the point:
Therefore:
Therefore, the vertex is:
Going through long division: We see that 21 goes into 52 twice, with a remainder of 10. Bringing down the first 0 after '21,' we have '100' to divide by 21; the quotient is 4 and the remainder 16. Bringing down the 2nd '0' after 21, we now have '160' to divide by 21; the quotient is 7 with a remainder of 13. So far we have 2.47 as our quotient. We can continue this process as far as desired.
Divide 21 into 52 with a calculator to check your work here.
52 divided by 21 is 2.48 after rounding up.
She should use Mean. This is where you add all of the numbers, then divide it by the number of numbers. Her average score is 80.75, or rounded to 81.
