## What are examples of exponential functions in real life?

Compound interest, loudness of sound, population increase, population decrease or radioactive decay are all applications of exponential functions.

### What is dilation of exponential function?

A dilation in the x-direction from the y-axis with factor k maps (x,y)↦(kx,y). The plane is stretched out horizontally from the y-axis by a factor of k. A dilation in the y-direction from the x-axis with factor k maps (x,y)↦(x,ky). The plane is stretched vertically from the x-axis by a factor of k.

#### What are the 3 most common applications of exponential functions?

Three of the most common applications of exponential and logarithmic functions have to do with interest earned on an investment, population growth, and carbon dating.

**What is exponential functions with examples?**

Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent. An example of an exponential function is the growth of bacteria. Some bacteria double every hour.

**What is the importance of exponential function in real life situation?**

The best thing about exponential functions is that they are so useful in real world situations. Exponential functions are used to model populations, carbon date artifacts, help coroners determine time of death, compute investments, as well as many other applications.

## What is the importance of exponential growth in the life of human beings?

Exponential population growth is very much important and critical to living world as we all know that current population of world is exceeding the carrying capacity of earth due to its exponential growth which is resulting in severe food crisis, water scarcity and economic fall down of the planet earth.

### How do you describe dilation?

A dilation is a transformation that enlarges or reduces the size of a figure. Therefore, the image and preimage will have the same shape but different sizes. Dilations also scale all sides of a figure by the same factor. As a result, dilations preserve angle measures and the ratio between corresponding parts.

#### What are two uses of exponential models in the real world?

Exponential functions are useful in modeling many physical phenomena, such as populations, interest rates, radioactive decay, and the amount of medicine in the bloodstream.

**What do you think is the importance of knowing exponential function?**

Investors know the importance of an exponential function, since compound interest can be described by one. The formula A = p(1 + r)t is an exponential function in which the amount in the account (A) depends on the length of time (t) of an investment (p) deposited at a given rate (r).

**Why do we use exponential functions?**

Exponential functions are commonly used in the biological sciences to model the amount of a particular quantity being modeled, such as population size, over time. Graphs of experimental data are usually drawn with time on the x-axis and the quantity on the y-axis.

## How are exponential functions used in business?

In economics exponential functions are important when looking at growth or decay. Examples are the value of an investment that increases by a constant percentage each period , sales of a company that increase at a constant percentage each period, models of economic growth or models of the spread of an epidemic.

### What are the two types of dilations?

A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image.

#### How do you dilate a function?

For instance, if we want to dilate a function by a factor of A in the x-direction and then shift C to the right, we do this by replacing x first by x/A and then by (x−C) in the formula.

**How are dilations and functions related?**

This activity helps students understand dilations of functions, where a dilation is a vertical or horizontal stretch or compression. When a function is multiplied by a number, the shape of the graph will retain its basic shape, though stretch or compress in different directions.

**Whats does dilation mean?**

enlarging, expanding

Definition of dilation : the act or action of enlarging, expanding, or widening : the state of being dilated: such as.

## How can we use exponential and logarithmic functions 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).

### Why is understanding of exponential function important in our daily lives?

#### How are exponential functions used in economics?

**How many types of dilations are there?**

two types

Dilation can be of two types: Expansion – When the size of an object is increased. Contraction – When the size of an object is decreased.
