Other Non-Linear Graphs: Overview

In this topic, we discuss plotting cubic graphs, sketching cubic functions. We learn using graphs to solve higher-order equations. It further talks about exponential graphs using several examples.

Bacteria multiply rapidly because a cell divides into two cells and then those two cells divide to each produce two more cells and so on. The growth rate is exponential and we can express the population of bacteria over time using the formula P=2t (t is the period of time).
