In this worksheet you'll be investigating what happens to a function when "a" is added to the end of it.
Try each clicking on each function in turn. Then move the "a" slider positive and negative. What happens when the "a" is positive? What happens when the "a" is negative?
Write in your own words what happens each time. Based on what you've seen, do you think this works for all functions?
