Percent Increase and Decrease
This worksheet has 14 problems where students need to find the percent of change between two numbers. There are three levels: level one has 9 problems, and the math is simpler. Level 2 has 3 problems that have more difficult division, and Level 3 has two challenge problems (again, more difficult division). I've included an answer key.

Properties and Characteristics of Functions
This worksheet covers several topics related to functions and their graphs. These topics include: domain, range, positive, negative, increasing, and decreasing intervals, extrema, end behavior, asymptotic behavior, inverses (graphs), one-to-one, symmetry (graphic and algebraic), and finding domains algebraically. I used it for extra credit practice before a quiz in Algebra 2 Honors.

I looked all over for a chart that shows the characteristics of the parent functions and did not come up with anything that included everything I needed so I created this chart. It is six pages with each parent function on a separate page. The characteristics are domain, range, interval of increase, extrema,end behavior, y intercept, x intercept, rate of change, and symmetry. This was extremely helpful for my students when they were comparing the parent functions using a Venn diagram and stud
