| 17) The graph of x=y^2-4 is a sideways hyperbola. To find the "p" of for x=0, just plug it in:
0=y^2-4
4=y^2, y=2 or -2
Likewise, 5=y^2-4, 9=y^2, y=3 or -3
You know the hyperbola connects between (0,2) and (5,3) and between (0,-2) and (5,-3). Looking at a graph, the steepest line is between (0,-2) and (5,3).
The slope of that is: (-2-3)/(0-5)=-5/-5=1 |
