f(x) = a(x - 4)^2 + 9
f(5) = 11 = a(5-4)^2 + 9
11 = a + 9
a = 2
f(x) = 2(x - 4)^2 + 9
= 2(x^2 - 8x + 16) + 9
= 2x^2 - 16x + 32 + 9
= 2x^2 - 16x + 41
f(5) = 11 = a(5-4)^2 + 9
11 = a + 9
a = 2
f(x) = 2(x - 4)^2 + 9
= 2(x^2 - 8x + 16) + 9
= 2x^2 - 16x + 32 + 9
= 2x^2 - 16x + 41

Same steps as your other question, just different values.
