What is the parent graph and equation for an exponential growth equation

The video tutorial explains exponential growth, starting with the basic formula y = b^x, where b > 1. It discusses the characteristics of exponential growth graphs, including their increasing nature and Y-intercept at (0,1). The tutorial also covers transformations of exponential graphs, such as shifts and stretches, using the formula y = a * b^(x-h) + k. These transformations affect the graph's position and shape, similar to quadratic functions.

Describe how the graph of an exponential function behaves as 'x' approaches negative infinity.

What transformations can be applied to the exponential function as described in the text?
