## Introduction To Exponential Functions

In this post, I am going to introduce you to the concept of exponential functions. A function that use exponents is the exponential function and it has many uses while calculating growth. You can determine, how fast something is growing with these kinds of functions. When it comes to calculating growth of something like population, … Read more

## Understanding Limits and Continuity

Limits and continuity of function is where calculus topics starts, however, to know calculus you must complete all lessons of pre- calculus with examples. Limit of a function is a certain value that a function approaches, whereas a function is said to be continuous when the function has no breaks or drawn without taking the … Read more

## Equations of Circle

In this article, you will learn about distance formula , midpoint , and equations of circle. The circle is a geometric shape that has a special significance in mathematics. To study the circle, in algebraic form, we need to define it in terms of coordinates in a 2d coordinate system also known as Cartesian coordinate … Read more

## Composite Functions

In this article, we you will learn about composite functions, it means that a function can become input of another function. Before you learn about the composite functions, you must be familiar with the arithmetic of functions which means given two function , you will be able to perform basic arithmetic operations on the function … Read more

## Intercepts and Symmetry of Graph

In the previous lesson, you learned about graph of equations which is points on a Cartesian plane. The graph of equation has some other interesting characteristics. You will learn about two such properties in this lesson – Intercepts and Symmetry of Graph. Intercepts The intercepts are the points where graph touches the x-axis or y-axis. … Read more

## Graph of Equations

In the previous lesson, you learned about co-ordinate system. You know than a point is plotted on Cartesian plane with x-axis and y-axis. A point has two values – and . For example, is a point. Graph of Linear Equations Therefore, expressions involving two variable can also be plotted using the Cartesian plane known as … Read more
