Understanding Linear and Exponential Functions

This video tutorial compares linear and exponential functions, focusing on their forms, properties, and graphical representations. It explains linear functions in slope-intercept form and exponential functions in general form. The tutorial uses tables of values to illustrate how linear functions increase by a constant amount, while exponential functions grow by a constant factor. It also discusses the domain and range of these functions and compares increasing and decreasing functions, highlighting exponential growth and decay.

What is the general form of a linear function?

• f(x) = mx + b

• f(x) = x^2 + bx + c

• f(x) = a * b^x

• f(x) = ax^2 + bx + c
