Check the discriminant, (), If less than zero, the graph does not intersect the and therefore has no intercepts. If not less than zero, solve the quadratic equation for the two values of the intercepts.

Where your function is in the form , obtain the -coordinate of the vertex from . Obtain the -coordinate of the vertex by evaluating the function at

The -intercept of is (from setting )
