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

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)
