Answer:

Explanation:

Parabolas can be written in the form


y = a(x-h)^2+k

The vertex is (h, k). The vertex in the graph is (5, 0).

so far, we have


y = a(x-5)^2+0\\y = a(x-5)^2

The other points we are given are (6, 1), (7, 4), (8, 9)


9 = a(8-5)^2\\9 = a(3)^2\\9 = 9a\\a = 1\\\\4 = a(7-5)^2\\4 = a(2)^2\\4 = 4a\\a = 1\\\\1 = a(6-5)^2\\a = 1

In vertex form


y = (x-5)^2\\y = x^2 - 10x + 25
