The parabola has a minima, vertex and a y-intercept.

Given,

Since the equation is quadratic, the parabola has a vertex. To find it, do as follows:

x = -b/2a

Where:

a=1

b=-2

Then:

x = -(-2)/ 2 × 1 = 1

Substitute this into the equation to obtain y:

y = 1² - 2 × 1  + 3 = 2

The point of the vertex is (1,2)  

The sign of a is positive, therefore, the parabola has a minimum.

Substitute x=0 into the equation to find y-intercept:

y = 0² - 2 × 0 + 3

y = 3

You know that this point is (0,3)

Recognize that the parabola has a minimum, a vertex, and a y-intercept, and that you may graph it as shown in the accompanying image.
