How do you find the vertex of y=x²-2x 3? what is it

The vertex is the point (1,2), but you have to graph it to find out what the vertex is

To find the vertex, use the vertex formula: x=-b/2a
a=1, b=-2, c=3
x=-(-2)/2(1)
x=1
The x-coordinate of the vertex is 1.
To find the y-coordinate, plug in 1 for every x in the equation:
y=(1)^2-2(1)+3
y=1-2+3
y=2
The y-coordinate is 2.
The vertex is (1,2)
