Cubic Graphs - Recognising, Sketching and Interpreting WORKSHEET DESCRIPTION
Deepen students' knowledge of graphs of cubic functions with this worksheet.
Section A asks learners to recognise cubic graphs as they have to select cubic graphs from a selection of eight different graphs. The other functions are linear, quadratic, reciprocal and exponential.
In section B, learners label features of a cubic graph with given keywords such as root and y intercept.
Then students will read values from a given graph of a cubic function such as the roots and interpret these as solutions.
Section D uses y intercepts to match three graphs to three equations.
The worksheet closes with an extension where students will use their knowledge to sketch the graph of a cubic function by using its solutions, roots and y intercept.
