- For the first curve:
- Moving from left to right, the curve is in quadrant 3.
- As x decreases, the curve approaches the line y equals negative 1.
- As x increases, the curve approaches the line x equals negative 1.
- For the second curve:
- Moving from left to right, the curve passes from quadrant 2 to quadrant 1 to quadrant 4.
- As x decreases, the curve approaches the line x equals negative 1.
- As x increases, the curve approaches the line y equals negative 1.
- The 2 curves pass through the following points:
- (negative 6 comma negative nine fifths)
- (0 comma 3)
- (4 comma negative one fifth)
