This algebra 2 math video tutorial provides an introduction into function notation. It discusses evaluating functions with a single variable x and using 2 variables x and y. It explains how to find the missing x or y variable using techniques such as factoring trinomials, GCF, and by grouping in addition to using the quadratic formula. This video contains plenty of examples and practice problems.
