y=(x12)27214

Explanation:

Given

y=x2x72

Find the Vertex

X-cordinate of the vertex

x=b2a=(1)2×1=12
At x=12;y=(12)21272=141272=7214

Vertex for of the quardratic equation is

y=a(xh)+k

Where h is xcordinate and k is y coordinate
a is the coefficient of x2

h=12
k=7214
a=1

Substitute these values in the formula

y=(x12)27214
