input can be a polynomial: General form: x^2-4*X-5 Standard form: (x -2)² -9 factored: (x+1)(x-5) coefficients: 1;-4;-5 or an equation: parabola transformational form: (Y +9) = (x -2)² circle: x^2 +y^2 = 9 ellipse: 9x2 +16y2 = 144 hyperbola: 9x2 -16y2 = 144 or for parabolas: Focus: (2, -8.75); Directrix: y = -9.25 Vertex (minimum): (2, -9) point (-1, 0) Vertex (minimum): (2, -9) Focus: (2, -8.75); Points: (-1, 0), (2, -9), (5, 0)
