8.1: Exploring the Logarithmic Function When a> 1, the exponential function and logarithmic function are increasing When 0< a <1, the exponential and logarithmic functions are decreasing When a< 0, the exponential and logarithmic functions are decreasing As well know how to find the inverse of a function Original function y=ax Inverse X= ay

8.2:Transformations of Logarithmic Functions Logarithmic function is written as f(x) = log10x Domain: if the function is to the left of the asymptote then x< d If the function is to the right of the asymptote then x> d Range: The range for a transformed logarithmic

8.3: Evaluating Logarithms Remember: Logarithms of negative numbers do not exist because a negative number can’t be written as a power of a positive base Any time you are given log x it means log10x Examples when a> 0 and a ≠ 1 Loga1 = 0 Logaax = x alogax = x
