Answer:

a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic, is a polynomial function with one or more variables in which the highest-degree term is of the second degree

Step-by-step explanation:

The minimum point exists if a>0. It is (h, k). So h=2, k=5

If y=a(x-2.5)^2+5 passes through (1,9) we have

9=a(1–2.5)^2+5.

From this we find a.
