The vertex form of a quadratic function is f(x) = a(x - h)2 + k. What is the vertex of each function? Match the function
rule with the coordinates of its vertex.
f(x) = 9(x - 5)2 + 6
(5.-9)
f(x) = 9(x + 5)2 - 6
(-9,-5)
f(x) = 6(x + 9)2 - 5
(-5, -6)
f(x) = 6(x - 5)2 - 9
(5,6)
f(x) = 5(x - 6)2 +9
(6,9)
