Graph Transformations and Function Evaluation

The video tutorial covers various mathematical concepts that will be tested, including plotting points on a coordinate plane, graphing different types of functions, evaluating and performing operations on functions, determining if functions are even, odd, or neither, finding the domain of functions, and sketching graph transformations. The teacher provides detailed explanations and examples for each topic to prepare students for the upcoming test.
