Answer:

The value of k is 5.

Step-by-step explanation:

Since we know we can convert function's quadratic form to vertex form by completing the square.

f(x)=x2?6x+14

We will add and subtract 9 to our equation in order to complete the square.

[tex]1(x^{2} ?6x+9)-9+14[/tex]

Upon completing the square and combining like terms we will get,

[tex]1(x?3)^{2} +5[/tex]

Upon comparing Willie's vertex form with our expression we can see that k is 5.

Therefore, the value of k is 5.
