Differentiate both sides with respect to
, treating
as a function of
:




At the point (0, 0), the derivative is

First, take two points from the graph. Call these points (a, b) and (c, d).
Next, find the slope. You can find this by doing (b-d)/(a-c).
Call the slope m. You will need this later.
Make an equation in slope intercept form (y = mx + b).
Now, take one of the points, and plug it into the equation.
mx + b has the same m as the slope.
From here, you can figure out b (the y-intercept).
To make a system, you do the same thing, but find where it is greater and lower.
