The video tutorial introduces the concept of exponential regression, explaining how to use technology, specifically a TI-84 graphing calculator, to write exponential functions. It covers the components of exponential functions, such as the initial amount and growth rate, and demonstrates how to analyze graphs to determine whether a function represents growth or decay. The tutorial provides step-by-step instructions for using a calculator to perform exponential regression, including entering data and interpreting results.

What is the primary focus of exponential regression in algebra?

• Calculating derivatives

• Using technology to write exponential functions

• Solving linear equations

• Finding the area under a curve

In the formula y = a * B^x, what does the 'a' term represent?

• The growth rate

• The decay rate

• The initial amount or y-intercept

• The slope of the line

How can you determine if an exponential function is increasing?

• If the 'B' term is greater than one

• If the 'B' term is equal to zero

• If the 'B' term is less than one

• If the 'a' term is negative

What is the first step when using a TI-84 calculator for exponential regression?
