You can put this solution on YOUR website! IF we replace x with zero we get y = 0+0+1 =1. The point (0,1) is called they Y intercept.
IF we set y = 0, we get the second part of the equation that is supposed to be equal to zero. That is a quadratic equation and there is not any real number solution to this quadratic equation as the number under radical would be a negative number. This means that there is not any x intercept.
In terms of graph, it means that curve doesn't touch the x axis. In other words Y can't be zero.
