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

match the function rule with the coordinates of its vertex

Step-by-step explanation:

1. f(x) = 9(x-5)^2+6 goes with (5,6)

2. f(x) = 6(x-5)^2-9 goes with (5,-9)

3. f(x) = 6(x+9)^2-5 goes with (-9,-5)

4. f(x) = 5(x-6)^2+9 goes with (6,9)

5. f(x) = 9(x+5)^2-6 goes with (-5,-6)

lockers 1, 4, 9, 16, 25, 40, and 49 are open
