Think-Pair-Share: Forms of Quadratic Functions

THINK (2 minutes): Examine f(x) = x² - 4x + 3 in three forms: Standard Form: f(x) = x² - 4x + 3 Factored Form: f(x) = (x - 1)(x - 3) Vertex Form: f(x) = (x - 2)² - 1 What key features does each form reveal most clearly? PAIR (3 minutes): Discuss with your partner: • Which form shows the y-intercept most easily? • Which form reveals the roots (x-intercepts)? • Which form shows the vertex coordinates? SHARE (5 minutes): Present your insights to the class
