In this mathematics lesson students learn about plotting exponential graphs on Cartesian axes. As learning progresses they begin to model exponential growth and use the graphs to find approximate solutions to exponential equations.
Differentiated Learning Objectives
- All students should be able to plot an exponential graph in the form y=kxwhere x ≥ 0.
- Most students should be able to plot and recognise the properties of an exponential graph in the form y=kx.
- Some students should be able to model and solve exponential functions graphically.
