Draw the graph of following function. Y=X²- 2X​

Plot 3 points

Step-by-step explanation:

Let plot the vertex

Plug this value in

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.

So this means point (0,0) is a point. Since 1 is the line of symmetry, (2,0) is a point.
