You can see some applications in the related sections panel at right.

Exponential logarithmic functions math. Rewrite each exponential equation in its equivalent logarithmic form. Know that the inverse of an exponential function is a logarithmic function. Which is read y equals the log of x base b or y equals the log base b of x in both forms x 0 and b 0 b 1. Get step by step solutions to your exponential and logarithmic functions problems with easy to understand explanations of each step.

The log of multiplication is the sum of the logs. Radicals rational exponents graphs end behavior of exponential functions manipulating exponential expressions using exponent properties exponential growth decay modeling with exponential functions solving exponential equations logarithm properties solving logarithmic equations graphing logarithmic functions logarithmic scale. F x 3 x decreases as x decreases and increases as x increases. Change of base.

How about the function f x 3 x. Exponential and logarithmic functions. Today logarithms are still important in many fields of science and engineering even though we use calculators for most simple calculations. Modeling exponential decay modeling exponential decay with the exponential function y ab x logarithmic functions this section will define evaluate simplify expand and solve logarithmic functions.

The log of division is the difference of the logs. Exponential and logarithmic functions. Does the function f x x increase or decrease as x increases or decreases. Log a m r r log a m the log of m with an exponent r is r times the log of m.

Solve exponential and logarithmic functions problems with our exponential and logarithmic functions calculator and problem solver. Represent exponential and logarithmic functions that model real world situations using graphing technology and describe their inverse relationship. Graphs of exponential and logarithmic equations. The meaning of logarithms.

A logarithmic function of the form latex y log b x latex where latex b latex is a positive real number can be graphed by using a calculator to determine points on the graph or can be graphed without a calculator by using the fact that its inverse is an exponential function. This just follows on from the previous division rule because log a 1 0. Log a m n log a m log a n. Log a 1 n log a n.

F x x increases as x decreases and decreases as x increases.
