If your students can't remember the difference between domain and range, then here's a video for you. Scholars learn to identify the domain and range of nine basic function types: constant, linear, absolute value, quadratic, cubic, square root, cube root, reciprocal, and squared reciprocal functions. They see how to determine domain and range by projecting the function onto the x- and y-axes.
