# Quick Answer: What Is The Difference Between Exponential And Logarithmic Graphs?

## What strategy are you using to get the graph of exponential or logarithmic functions?

One of my strategies I use to get the graph of exponential or logarithmic functions, is to start with a table.

I think of my table columns as an input and output.

I do this by creating a t-chart with x and y to represent my columns..

## How do you know if a graph is a logarithmic function?

The inverse of an exponential function is a logarithmic function. Remember that the inverse of a function is obtained by switching the x and y coordinates. This reflects the graph about the line y=x. As you can tell from the graph to the right, the logarithmic curve is a reflection of the exponential curve.

## How do you tell if a graph is exponential or logarithmic?

Key TakeawaysIf the base, b , is greater than 1 , then the function increases exponentially at a growth rate of b . … If the base, b , is less than 1 (but greater than 0 ) the function decreases exponentially at a rate of b . … If the base, b , is equal to 1 , then the function trivially becomes y=a .More items…

## How do you do exponential graphs?

Graphing Exponential FunctionsReplacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.Replacing x with x+h translates the graph h units to the left.Replacing y with y−k (which is the same as adding k to the right side) translates the graph k units up.

## What does a logarithmic graph look like?

The logarithmic function may look like the graph below. The negative in front of the function reflects the function over the x-axis, but all other properties of the logarithmic function hold. Here, as a decreases, the magnitude of a increases. As this happens, the graph decreases at a quicker rate as x increases.

## What is the relationship between exponential or logarithmic equations?

Logarithmic equations can be written as exponential equations and vice versa. The logarithmic equation logb(x)=c l o g b ( x ) = c corresponds to the exponential equation bc=x b c = x . As an example, the logarithmic equation log216=4 l o g 2 16 = 4 corresponds to the exponential equation 24=16 2 4 = 16 .

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

Exponential and logarithmic functions are no exception! 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 difference between linear and logarithmic scale?

On a linear scale, the value between any two points will never change. A logarithm, or log, is based on exponents, which are the superscripts next to, and above, another base number or variable. On a logarithmic scale the value between two points changes in a particular pattern.

## What is an exponential graph?

In an exponential graph, the “rate of change” increases (or decreases) across the graph. Characteristics of Exponential Functions. The graphs of functions of the form y = bx have certain characteristics in common. Exponential functions are one-to-one functions. • graph crosses the y-axis at (0,1)

## 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.

## What does a exponential graph look like?

An exponential growth function can be written in the form y = abx where a > 0 and b > 1. The graph will curve upward, as shown in the example of f(x) = 2x below. … The basic shape of an exponential decay function is shown below in the example of f(x) = 2−x. (This function can also be expressed as f(x) = (1/2)x.)

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

Logarithmic growth is the inverse of exponential growth and is very slow. grow logarithmically. … 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.

## What is the relationship between the log and exponential 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 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 do you explain logarithmic scales?

A logarithmic scale (or log scale) is a way of displaying numerical data over a very wide range of values in a compact way—typically the largest numbers in the data are hundreds or even thousands of times larger than the smallest numbers.
