Section 11-4 Logarithmic Functions

Vocabulary Logarithm – y is called this in the function Logarithmic Function – The inverse of the exponential function. Common Logarithm – logarithms that use ten as the base Characteristic – the exponent of 10 that is used to write the number in scientific notation Mantissa –the common logarithm of a number between 1 and 10
