Answer:
Step-by-step explanation:
<u>Vertex form of a quadratic equation</u>:
where:
- (h, k) is the vertex
- a is some constant
<u>Given vertex</u>: (2, -6)
⇒ h = 2 and k = -6
Substitute the values of h and k into the formula:
As we have not been given a value for the constant , assume this is 1.
Therefore, the <u>vertex form</u> of the <u>quadratic function</u> with vertex (2, -6) is:
