Nice nice 
You could add some more explanation, maybe...
Something like this, based on your example:
Your a value: 32
Your b value: 64
Your c value: 54354
General form: 32x^2+64x+54354
Because the a-value is positive/negative, this graph has a minimum/maximum
Domain: {x|xER}
Range: {y|y>=54322,yER}
The discriminant is b^2 - 4ac = 64^2 - 4*32*54354 = -6953216, therefore the quadratic equation has no real solutions (and then show the complex roots solutions) (and if the discriminant is positive, show the formula's and calculations for both solutions, and if the discriminant is negative, show the formula and calculation for the one solution)
And so on... I wanna see formula's! 
Oh, and for the graph in your example, you might want to indicate that it's not a "real" graph (since it's supposed to be with imaginary numbers and stuff)...
