Switching Between Forms of Quadratic Functions

(18) Find the vertex of the function as well as the equation for the axis of symmetry. Write whether it is a least or greatest value of the function. x2 – 2x – 8 = 0. Vertex: (1, -9) Axis of Symmetry: x = 1. Least value (19) Find the vertex and axis of symmetry. Use the vertex and at least four other points to graph the equation. x2 – 4x ... ................
