Find Exponential Equation Through 2 Points -Ti-83/Ti-84- Exponential Regression f(x)=ab^x 'How to'

This video provides an example of finding the exponential function f(x) = a*b^x through the two points (3, 7) and (5, 20). The explanation here requires a Texas-Instruments TI-83 or TI-84 Graphing Calculator. ...Pro-Tip: To skip the introduction start at 01:55

My video doing exponential regression using algebra.

For f(x) = ab^x
a = the y-intercept
b = the "growth rate"

THANK I PASSED MY QUIZ BECAUSE OF THIS VIDEO

[sageely]

It's always the old videos that are the helpful ones

Exponential from Two Points (Level 2) is there anyway do do this on the ti 84?
