The video tutorial explains exponential and linear functions using real-world examples. It covers the parameters of exponential functions, such as base, vertical translation, and Y-intercept, using the growth of bacteria. It then introduces linear functions with a focus on slope and Y-intercept, using the population of zebras as an example.

• Exponential function

• Linear function

• Logarithmic function

• Quadratic function

How is the Y-intercept of the exponential function y = 12 * 3^x + 5 calculated?
