Whenever the derivative, also called the slope function reaches

You can find the derivative by remembering:

if

While numbers without

Going from there, the derivative of your function is:

Enter this in your GC as

Now, on your GC you go find the zeroe-values (there's a menu for that)

Since your equation is 7th grade (because of
