Can a graphing calculator be used to solve any quadratic equation?

For the most part it can. if you have a TI-83 or better, you can use the solver under your math button. All you have to do is plug in the equation that is set to equal zero!

What are the pros and cons of using the substitution or elimination method in equations?

A pro for solving equations through graphing can allow one to visualize problems which can allow one to make better sense to the problem. However, fractions, and decimals can be very difficult to plot accurately. Furthermore, solutions could fall outside of the boundaries of a graph making them impossible to see with a graph. A pro for solving equations through either the methods of substitution and elimination allow one to achieve an exact answer regardless of fraction, decimal, or integer. However, by using these methods one will have a more difficult time with visualization without the use of a graph.

If fx is a parabola then how would you go about graphing it?

I would draw up a simple table -5 -4 -3 -2 -1 0 +1 +2 +3 +5 +6 Then substitute these values into the equation and that will give you pairs of coordinates which you can plot. Of course, the numbers you choose for the top row of your table (the x values) will depend on the actual equation. This set of numbers I have showed above may not fit. If you care to give an actual example, I can give you a better answer.
