Throughout this worksheet learners will determine whether functions are linear or nonlinear. In Section A, pupils will decide whether 9 graphs are linear or not. In Section B students are given 9 equations. Lastly, Section C introduces tables of values where students will analyse how changes in x affect y to determine if the relationship is linear.
Nonlinear functions include: quadratics, cubics, exponential and reciprocal.
See our worksheet “Recognising Cubics, Quadratics, Reciprocals and Straight Line Graphs” for more on this topic.
