Transformations of Exponential Graphs
The activity encourages learners to explore the effect of changing a coefficient in the equation y = A + Bekx in terms of a transformation of the graph y = ex. The main activity involves matching the graphs drawn without scales on the learner worksheet to the functions on cards. The learners must write scales onto their graphs based on the equations. The second task asks learners to describe the transformations from the equation and sketch graphs. An extension activity looks at the points of intersection of exponential graphs.
