Quadratic Graphs - Roots and Y-Intercept

This video tutorial explores the relationship between quadratic equations and their graphs. It explains how the sign of the X squared term determines the graph's shape, either U-shaped or N-shaped. The video covers how to identify roots and the Y-intercept from the equation, which aids in sketching the graph. It also provides practice exercises for sketching quadratics and hints at future topics like turning points and symmetry.
