Point 5 of 5

22.2.5 When k<0: Second and Fourth Quadrants

Core idea

When k is negative, the two branches run off to upper-left and lower-right, with x and y opposite in sign, one rising as the other falls.

Module goal. Plot the hyperbola point by point and get to know its shape: two separate branches that never touch the axes.
