Comparing 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 covers the graphical behavior of these functions, highlighting the differences in their domains and ranges. The video concludes with a comparison of decreasing linear and exponential functions, emphasizing the concepts of negative slope and exponential decay.

What is the general form of a linear function?

• f(x) = a + bx

• f(x) = mx^2 + b

• f(x) = mx + b

• f(x) = a * b^x
