Graph Transformations and Effects

Mrs. Ephraim, a math teacher, uses songs to help students remember mathematical concepts. In this video, she introduces a song to the tune of 'We Wish You a Merry Christmas' to teach students about shifting graphs, a topic typically covered in Algebra 2. The song explains how different mathematical operations affect the position and shape of graphs, such as moving them horizontally or vertically and changing their shape. The video concludes with a thank you message.
