Investigation of af(x)

This is an investigation of the effect "a" has in af(x). That is multiplying an entire function by "a". Be careful when examining the linear function. It looks to be rotating... but is there another explanation? Check the other functions to find out. What does increasing the value of "a" do to our function? What does decreasing the value of "a" do to our function? What does a negative "a" value do to our function?
