... what happens to the y-values as x approaches positive infinity () and negative infinity (-), the ends of the function. Let’s look at our example. As x approaches infinity (imagine travelling to the right on the line), what happens to values of y? They get larger or we can say that they approach in ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
