Overview Composition of Functions

Learn how to compose two functions where one or both of those functions is/are quadratic. To compose two functions means to express one of the functions as a function of the other function. This is done by replacing the input variable of one of the functions with the value of the second function. We will then simplify the composition and determine the domain.

Hello Mr. McLogan. Love your videos they are helping me a lot. I’ve been getting very frustrated and stuck in my Precalc/Trig class the teacher is a great but I’m not grasping it fast. I’ve struggled with my own issues and I’m trying to better myself and continue to be hard on myself, I tend to draw a blank when doing the homework and it’s turns into frustration. If you have any suggestions to help me learn and figure it out it would be greatly appreciated it I know it’s an old post but I hope you see this. I also freeze up when we take tests. Does doing the homework continuously help build a better understanding or doing a few types of problems that are tough build a better understanding? Thank you.
