Find points on the graph of the function where the slope is 3. My first instinct would be to do the derivative of , which would be . But this does not help in finding the points of the function where the slope is 3.

Set the derivative equal to the slope. x=1,-1 plug these 2 points back into the original equation to find the points.
So the points are ? I would never have figured that out.

Of course it seems obvious now.
