Set up the equation in the example below and then change the value of n by
dragging the slider knob. Play the animation, too.


What does the n do to the curve? What if n is positive? Which way does the curve move? What if n is negative?

If you had difficulty graphing the function, here is an example of what it looks like in NuCalc. You will need to configure NuCalc Web Helper as a helper application in your brower first.


Now we'll look at a different situation.



Set up the window as before, but this time, instead of
Answer the same questions: What does the n do? And again, what if n is positive? What if it's negative?

Let's try another function and see if we can slide it back and forth.

Try these expressions:

Again, see what happens when n is positive and negative. How would you change the function to make it slide up and down?

  1. What's the rule for making a function slide up and down?
  2. What's the rule for making a function slide back and forth?

What if there is more than one x in an expression? Try it. First graph


Then see if you can slide it back and forth. Try these expressions:

The lessons should be:

To make a curve slide to the right, subtract the distance you want it to slide from every x in the expression.

To make a curve slide up, add the distance you want to slide it to the entire expression.
