Use the checkboxes to show the graphs of the functions one at a time. Each function will have a point that you can drag along the function. A point, marked as a prime point, will show the rotation of the point 180° around the origin. A function is equal if the rotations of the point always map back onto the graph itself. 1. Which functions are even - y = |x|, cos(x), or sin(x)? 2. The third checkbox displays the equation y = x to the nth power. Change the value of n. a. What happens when n is a positive even number? b. What happens when n is a positive odd number? c. What happens when n is a negative even number? d. What happens when n is a negative odd number?
