To graph a parabola you must find the axis of symmetry, determine the focal distance and write the focal as a point, and find the directrix. These are all the main points you need to be able to draw a parabola.
If you can mash the equation for the parabola into the form Y = Ax2 + Bx + C, then the parabola opens up if 'A' is positive, and down if 'A' is negative.

To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the right of the vertex.
You need more than one tangent to find the equation of a parabola.
Depending on the domain and range, the inverse may or may not be defined. Assuming it is defined, the inverse function can be derived as follows: The negative parabola is y = -ax2 + bx + c (where a>0) so that -ax2 + bx + c - y = 0 using the quadratic formula, x = [-b ± sqrt(b2 + 4*a*(c-y)]/(-2a) which is a square root function, and will be real provided that b2 + 4*a*(c-y) > 0

Select a set of x values and find the value of y or f(x) - depending on how the parabola is defined. These are the values that you need to graph.
