This hand-drawn, teacher-style poster clearly compares linear and non-linear functions using simple language, colorful annotations, and easy-to-follow visuals. On the left side, linear functions are explained with a straight-line graph, the equation form y=mx+b, and a table showing a constant rate of change. On the right side, non-linear functions are illustrated with a curved graph (such as y=x2−6), along with a table demonstrating that the rate of change is not constant. The poster includes
