With only one squared term (and no xy terms), the graph of this equation will be a parabola.
Since the squared term is , this parabola will open to the right or left.
Since the coefficient of the squared term is positive, +1, the parabola will open to the right.
If you need to determine more about the graph, then complete the square for the y terms and put the equation in vertex form. This will tell you where the vertex is. If you need still more, then start building a table of values from which to plot additional points.
