 # Question: What Is The Difference Between Linear And Logarithmic Graph?

## Is ex logarithmic or exponential?

The exponential function f(x) = ex is the inverse of the logarithm function f(x) = ln x.

Exercises 1.

Sketch the graph of the function f(x) = ax for the following values of a, on the same axes.

2..

## How does a logarithmic scale work?

A logarithmic scale is defined as one where the units on an axis are powers, or logarithms, of a base number, usually 10. It is particularly useful when we need to represent large, exponential changes in information on that axis. A semi-log chart is one in which one axis (x or y) is converted to a logarithmic scale.

## Is logarithmic the same as exponential?

Logarithmic growth is the inverse of exponential growth and is very slow. … This terminological confusion between logarithmic growth and exponential growth may be explained by the fact that exponential growth curves may be straightened by plotting them using a logarithmic scale for the growth axis.

## How do you read a logarithmic graph?

By using the top plot, [H+] can be read directly from the X-axis; for example, at 45% saturation, [H+] = 1.0 x 10-5. By using this bottom plot, [H+] must be calculated by taking the antilog of the negative value of the log value read from the X-axis; for example, at 45% saturation, [H+] = antilog (-5.0) = 10-5.

## What is the difference between exponential and logarithmic graphs?

The logarithmic function is the inverse function of the exponential function. This is means that if a^x = b (exponential), then log base a (b) = x. (logarithmic). Therefore, exponential and logarithmic functions are not the same.

## What is the meaning of logarithmic?

A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because. 102 = 100.

## What does exponential growth look like on a logarithmic graph?

If you show exponential growth on an exponential scale – meaning, our log scale –, the exponential effect evens out. We get a straight line. That means: If you see a straight line in a log-scaled chart, something grows exponentially. Every minute/day/year, the amount of something will double (or halve).

## How are exponential and logarithmic functions used in real life?

Much of the power of logarithms is their usefulness in solving exponential equations. Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity).

## What is the slope of a logarithmic graph?

A plot of the logarithm of the freefall distance as a function of the logarithm of time yields a straight line of slope 2. … The slope of a log-log plot gives the power of the relationship, and a straight line is an indication that a definite power relationship exists.

## Why would you use a logarithmic scale?

There are two main reasons to use logarithmic scales in charts and graphs. The first is to respond to skewness towards large values; i.e., cases in which one or a few points are much larger than the bulk of the data. … The equation y = log b (x) means that y is the power or exponent that b is raised to in order to get x.

## What does a logarithmic graph tell you?

Same data, different perspectives But the logarithmic graph shows a flattening of the line much earlier because of the way the scale has been compressed. It also makes it possible to fit a large or widespread set of results onto a graph that might otherwise not fit in a linear way.
