First you need to improve your presentation. g(x) is ok for discussions, but a graphing program requires y. And people need spaces to improve readability. Then we use Shift-6 for powers.
y = x^3 - x^2 - 4x + 4

Well, programs have their rules. You didn't say what to solve, so the program just picked something. Let's try something more specific.

Just guessing now. Maybe when you said "solve" you meant to find the roots.
