Understanding Stretching and Shrinking of Graphs
This lesson focuses on vertical and horizontal stretching and shrinking of graphs. Students will learn to sketch graphs demonstrating these transformations. For vertical stretching and shrinking, they will multiply the y-values of each ordered pair by a given coefficient. For horizontal transformations, students will divide the x-values by the same coefficient. Through this process, students will understand how different coefficients affect the shape and position of a graph, enhancing their skills in graph analysis.
