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)
