Lesson_8.1_ExploringLogarithms.notebook 8.1 Exploring the Logarithmic Function What is the inverse of the exponential function y = a x ? We can rewrite the inverse of the exponential function as a logarithm (also known as a logarithmic function ). The following two statements are equivalent: x = a y y=log a x How do we rewrite exponentials as logarithms? y = log a x base exponent answer is equivalent to x = a y exponent = log base answer Memory Aid: eg. 3 2 = 9 becomes 2 = log 3 9
