===Below are some extra online resources that will help you to understand some of the more challenging topics in the ALEKS precalculus course. The top part is a "table of contents," and you'll have to scroll down to see the actual resource links. ===

=Table of Contents:=

1. COMPOSITION OF TWO FUNCTIONS (BASIC) - Text 2. COMPOSITION OF TWO FUNCTIONS (BASIC) - Video 3. EVEN AND ODD FUNCTIONS - Text 4. EVEN AND ODD FUNCTIONS - Video

=Resouce Links:= The link shows a more detailed explanation of the process of composition of functions. It also gives five practice problems and solutions. || [] || This video uses color-coding to help you visualize the process. It's tricky, so you may need to watch the video a few times. I suggest that you do the steps as the man in the example does and pause after each step to make sure you understand why he did what he did. Then try the next step on your own to see if you can get it correct. Then continue the video to see if you're right. See if this works for you. On your ALEKS lessons you may be asked to also substitute a number into the final composition to get a number as your final answer instead of just an expression like these examples show. Let me know if you need more examples. I'll be glad to provide more explanation. || media type="youtube" key="S4AEZElTPDo" height="315" width="420" || This site gives a little more background and explanation of even and odd functions. Don't get too lost in the notation, but take notice of the graphical ways of determining whether a function is odd or even or neither. || [] || This video shows how to use symmetry to determine whether the graph of a function is even, odd, or neither. || media type="youtube" key="KankeIx80MQ" height="315" width="420" ||
