Graphing Exponential and Logarithmic Functions

The video tutorial covers graphing exponential and logarithmic functions, focusing on transformations. It begins with a review of the parent exponential function, discussing its domain, range, and asymptote. The tutorial then explains how to perform transformations, such as vertical and horizontal dilations and translations, on exponential functions, with examples provided. The video transitions to logarithmic functions, introducing the parent function and its properties. Similar transformations are discussed for logarithmic functions, with examples to illustrate the concepts.

What is the domain of the parent exponential function?

• All real numbers

• All positive numbers

• 0 to infinity

• All negative numbers

What does the 'a' value represent in the transformation of an exponential function?

• Horizontal dilation

• Vertical translation
