Let point P be with coordinates
Find the equation of the tangent line.
1. If
then 
2. The equation of the tangent line at point P is

Find x-intercept and y-intercept of this line:
- when x=0, then

- when y=0, then

The area of the triangle enclosed by the tangent line at P, the x-axis, and y-axis is

Since point P is on the parabola, then
and

Find the derivative A':

Equate this derivative to 0, then

And

Answer: two points:
