Comparing Linear, Exponential, and Quadratic Functions

The video tutorial explains how to compare functions by identifying them as linear, exponential, or quadratic. It covers checking patterns in tables of values, identifying equations and real-life situations, and comparing functions using tables and graphs. The tutorial also discusses calculating slopes and y-intercepts to determine the greatest rate of change and where functions are equal.

What pattern in the table of values indicates an exponential function?

• Consistent second differences

• Multiplication pattern for f(x) values

• Constant subtraction across x values

• Constant addition across x values
