Answer:

Minimum, Vertex(1,-7) and sorry what do you mean by aos? i dont get that please type in the comments I'll answer that too. Hope you understand the rest

Explanation:

The vertex of a parabola means the stationary point/turning point which is denoted by the following:


x=(-b)/(2a) \\

and for y we just simply put the value of x that we get into the equation so lets get started

The equation
y=x^2-2x-6 is a quadratic equation

and if we compare it by the standard form
y=ax^2+bx+c we get the following values

a=1 , b=-2 , c=-6

and now for the vertex


x=(-b)/(2a)


x=(-(-2))/(2(1)) \\x=(2)/(2) \\x=1

and now for y


y=x^2-2x-6\\y=(1)^2-2(1)-6\\y=1-2-6\\y=-7

so the vertex is (1,-7)

and the graph is minimum not maximum because the value of a is greater than 0 if the value of a>0 then the graph is minimum and if the value of a<0 meaning a is negative the graph is maximum and here in the equation a=1 which means a>0 then our graph is minimum.
