# Write an exponential function in logarithmic form graph

However, if we put a logarithm there we also must put a logarithm in front of the right side. This is commonly referred to as taking the logarithm of both sides. The exponential function with base e is called the natural exponential function. This base is used in economic analysis and problems involving natural growth and decay. At this point, we are just going to learn how to find the value of e raised to an exponent using the calculator.

Since there are a lot of different calculators I will be go over the more common ones. At this point you need to check to make sure that you know how to use this key, because we will be using it heavily. The two main e keys found on calculators are you will only have one of these: Having to use the e key with the caret top key is most frequently found on graphing calculators but can be found on other types of calculators.

## Solve logarithmic equations, step-by-step

It should look like this on your screen: If you got If not, try again. If you still can't get it look in your reference manual that came with the calculator.

[BINGSNIPMIX-3

The key that looks like is most common in business and scientific calculators, but can be found on other types of calculators.

On most business and scientific calculators, the e function key looks like or very similar to this. Go ahead and try it out by finding e raised to the 5th power. Type in 5 and then press. You should have gotten Home; Calculators; Algebra I Calculators; Math Problem Solver (all calculators) Slope Intercept Form Calculator with Two Points.

The slope intercept form calculator will find the slope of the line passing through the two given points, its y-intercept and slope-intercept form of the line, with steps shown.

## Solve exponential equations, step-by-step

Online homework and grading tools for instructors and students that reinforce student learning through practice and instant feedback.

Figure mtb15.comed Fibonacci sequence approximated by exponential function for its range of values. The point we are making here is that both scales can be with some level of accuracy called “exponential”. Logarithmic Functions. A logarithm is simply an exponent that is written in a special way..

For example, we know that the following exponential equation is true: `3^2= 9` In this case, the base is `3` and the exponent is `2`. We can write this equation in logarithm form .

## Definitions: Exponential and Logarithmic Functions

Introduction. Function and arbitrary waveform generators are among the most important and versatile pieces of electronic test equipment. In electronic design and troubleshooting, the circuit under scrutiny often requires a controllable signal to simulate its normal operation.

*The Greatest Integer Function, sometimes called the Step Function, returns the greatest integer less than or equal to a number (think of rounding down to an integer).
