The video tutorial covers exponential growth and decay, explaining their formulas and graphing techniques. It discusses the concept of horizontal asymptotes and how they affect the graph. The tutorial also introduces exponential models used for real-life applications, such as calculating the value of a car over time. Finally, it explains compound interest, detailing how to calculate it using a specific formula.

What is the condition for a function to show exponential growth?

• The exponent must be negative.

• The base number must be less than one.

• The coefficient must be negative.

• The base number must be greater than one.
