Part 6: Graphing and Functions
A greater emphasis has been placed on conceptual questions and graphing on the AP exam. Below you will find
a few example concept questions that review foundational knowledge of graphs. Ideally you won’t need to
review, but you may need to review some math to complete these tasks. At the end of this part is a section
covering graphical analysis that you probably have not seen before: linear transformation. This analysis
involves converting any non-linear graph into a linear graph by adjusting the axes plotted. We want a linear
graph because we can easily find the slope of the line of best fit of the graph to help justify a mathematical
model or equation.
