Intro to Logarithmic Functions

Logarithmic functions are the inverse (reverse the positions of x and y) of exponential functions.

Using the Log of a exponent allows us to solve exponential equations algebraically instead of graphically (more on this to come later).

We

• investigated how Logarithmic functions compared to Exponential functions
• compared the Domain and Range
• compared the x and y intercepts
• compared what the a value represents in each situation
• exponential functions: a is the initial value
• logarithmic functions: a is the value of the function when x = 10 ( or when x= the value of the base of the log - more to come on this later)
