GCSE Maths - What are Quadratic Graphs? #76

The video tutorial explains quadratic graphs, highlighting their smooth curved shape and symmetry. It discusses how the sign of the x squared term affects the graph's orientation, with positive terms creating upward curves and negative terms creating downward curves. Basic quadratic graphs like y = x^2 and y = -x^2 are introduced, showing their axis crossing at the origin. The tutorial also covers how altering the equation changes the graph's shape, such as making it narrower or shifting its position.
