Answer:
Plot 3 points
Step-by-step explanation:
Let plot the vertex
[tex] - \frac{b}{2a} [/tex]
[tex] - \frac{ - 2}{2} = 1[/tex]
Plug this value in
[tex]y = {1}^{2} - 2 = - 1[/tex]
So our minimum point is at (1,-1).
This also means our line of symmetry occurs about x=1.
Let use some point like 0.
[tex]0 = {0}^{2} - 0[/tex]
So this means point (0,0) is a point. Since 1 is the line of symmetry, (2,0) is a point.
