Graphing Parabolas
Compare the given equation y = x^28x2 to above equation a = 1, b = 8, c = 2 Axis of symmetry is x = b/2a x = (8)/2(1) → x = 4 Vertex of parabola Substitute the x value in equation y = x^28x2 y = (4)^28(4)2 y = y = 14 → Vertex of parabola is (4,14) To find y intercept substiute x = 0 in y = x^28x2 y = (0)^28Start studying Standard Form Vertex, axis of symmetry, yintercept and tables for quadratics Learn vocabulary, terms, and more with flashcards, games, and other study tools Search Create Find the axis of symmetry for y=x²4x6 (0,6) Find the yintercept for y=x²4x6 up because a = 1 Does the parabola open up or down?
