Functions, Graphs, and Limits
Limits at Infinity
Vertical asymptotes occur where a function f(x) has a limit of infinity - that is, at values of a for which
We can also take limits as x goes to ∞ or -∞, written
These limits look at where the function f(x) is attempting to reach. Before we go into more depth with the function side of things, we'll look at some silly examples.
