Solution:

The vertex form of equation is given as:

Where, (h, k) is the vertex

Given that,

We have to find the vertex form of equation

Step 1:

Complete the square for

a = 1

b = -6

c = 14

Consider the vertex form of a parabola.

Substitute the values of  a and b into following:

Find the value of "e" using following formula:

Substitute the values of a, d, e in eqn 1

Thus vertex form form is found. Option C is correct
