Limits towards infinities

So, remember how alllllll those paragraphs before we talked about taking infinitely larger and larger or smaller and smaller values?

This is exactly what we'll denote as the limit towards infinity.

So, taking infinitely larger and larger values, in terms of limits, this will be the limit of a function f(x) as x tends to positive infinity:Similarly, taking infinitely smaller and smaller values, this will be the limit of f(x) as x tends to negative infinity: To properly put this concept to good use, let's introduce Growth Rate
