Let's do another one:
Graph | 2 things |
The y-intercept: Find f(0) |
The x-intercept: numerator = 0, solve. |
Vertical asymptotes: denominator = 0, solve |
Horizontal asymptote: |
Look at |
* When this is the case, we're going to be forced to "quickie plot" a few points to nail the graph. No, this isn't being a sissy -- we'll have no choice. But, Calculus will fix this problem by telling us where the graphs are increasing and decreasing!
