By "simplifying" an algebraic expression, we mean writing it in the most compact or efficient manner, without changing the value of the expression. This website explores "Like terms" and how to combine them in different ways.
This is a great website for learning about the graphs of rational functions. Shows you everything from the horizontal and vertical asymptote to the intercepts. It sketches it all out for you which makes it ten times easier.
Tells and shows graphs of what logarithmic functions look like. Also, gives you a graph and lets you plug points in and see what the graph looks like. Great way to find out how to use log functions.
This site gives properties of exponential functions and explains translations of exponential functions. It also covers natural base e, compounded interest, and growth/decay.
