# Exponential Growth

In this video, we are going to look at exponential growth.

$y=a \times (b)^x$
For a graph to demonstrate exponential growth, the coefficient, a, must be positive, and the base of the exponent, b, must be greater than 1. The graph will follow a path that curves upward to the right. These graphs grow by a factor, as opposed to a constant value.
For example:
The graph of
$y=2 \times (1.2)^x$
curves upward after plotting points as shown in the video, and demonstrates exponential growth. This graph grows by a factor of 1.2.
When comparing a linear graph to an exponential growth graph, as more time goes on, the exponential growth tends to grow by larger quantities than the linear growth.
