    I know that the open circles mean that it is less than the number and the open circles are equal to or to the number

    So (3,9) by counting the rise over run?

    Look at the given function ``` y = x - 1 if x < 2 y = x^2 if x greater than or equal to 2 ```

    try each option, the first option is (-1, 1) since the x value, -1 is less than 2, you need to use first case for working y : y = -1-1 = -2 so (-1, -2) is a point on the graph, not (-1, 1)

    So I did the diagram, so why can't 2,1 be a possible point? @ganeshie8
