Find x intercepts by solving the equation in standard form with y=0.
Find y intercept by just evaluating y for x=0.
The positive coefficient on the degree-2 term means that the vertex is a minimum.
Discriminant, is a perfect square and a positive value, telling you that the graph has two x-axis intercepts and they are integers.
