The vertex form of a quadratic function is flax) = 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
(6.9)
f(x) = 5(x - 6)2 + 9
(5.-9)
f(x) = 6(x + 9)2 -5
(5.6)
f(x) = 9(x + 5)2 - 6
(-9.-5)
f(x) = 6(x - 5)2 - 9
(-5, -6)
