Use the checkboxes to show the graphs one at a time. Each graph will have a point that you can drag to perform a vertical line test. A graph shows a function if the vertical line never passes through two points at once on the graph.[br]1. Which graphs are functions?[br]2. One checkbox displays the equation y = x to the nth power. Change the value of n. [br]a. What happens when n is a positive even number?[br]b. What happens when n is a positive odd number?[br]c. What happens when n is a negative even number?[br]d. What happens when n is a negative odd number?[br]3. In this interactive, what do all of the related that are not functions have in common?
