Logarithmic and Exponential Functions

The video tutorial covers solving logarithmic equations, building on previous lessons about logs and exponential equations. It introduces the Graph and Calc 83 app for calculations, reviews key concepts, and explains the log loop method. The tutorial also covers common logarithms, the change of base formula, and how to evaluate logarithmic expressions using a calculator. It addresses handling decimal exponents and provides practice instructions.

What is the relationship between logarithmic and exponential equations?

• They are unrelated.

• They are both types of polynomial equations.

• Logarithmic equations are the inverse of exponential equations.

• Exponential equations are a type of logarithmic equation.
