## Nonlinear Function: How do you know if a function is nonlinear?

A nonlinear function is most easily described as whatever is not a linear function. Learn what a linear function is and be able to define a nonlinear function; using examples, learn how to distinguish between the two. What are Linear Functions? The easiest way to define a nonlinear function is as a function that is … Read more

## How Do You Find The Discriminant of a Quadratic Equation?

The Discriminant When does ax2+bx+c=0 have a real solution? Well, we know how to find the solutions using the quadratic formula: x=−b±√b2−4ac2a. That makes it look like we can always get solutions. However, we can’t always exercise a square root! Sometimes you’ll see a negative number under the radical. A negative under the radical means there is no real … Read more

## Polar vs Non-Polar Bonds & Molecules: Definition and Examples

We explain the difference between polar and non-polar bonds in this chemistry tutorial. Then we will tell you what a polar molecule is, and what a non-polar molecule is. Last but not least, you discover what a dipole moment is. What do polar and non-polar bonds mean? In simple terms, polar means oppositely charged while … Read more

## Relations and Functions – Explanation & Examples

Relations and Functions are the most essential topics in algebra. Relations and functions – these are the two different words having separate meanings mathematically. You might get confused about their difference. Before we go deeper, let’s understand the variation between both with a simple example. An ordered pair is described as (INPUT, OUTPUT):  The relation … Read more

## Inverse Property of Addition: Definition and Examples

Inverse Property of Addition is what number you add to a provided number to make the sum zero. For instance, if we take the number 3 and add -3 to it, the result is zero. Therefore, the additive inverse of 3 is -3. We come across such positions in our daily life where we nullify … Read more

## What are the Key Differences Between DNA and RNA?

The nucleic acids ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) are among the most important molecules in cell biology, which are responsible for storing and transmitting genetic information in all living things. Despite the fact that they are both linear polymers containing sugars, phosphates, and bases, there are a few key differences between them. Both … Read more

## Geometric Sequence Formula: Progression, Series, & Examples

The geometric progression is a sequence in which every term bears a constant ratio to its predecessor. These sequences are referred to as geometric progressions. In order to get the next term in the geometric progression, we have to multiply with a fixed term known as the common ratio, every time, and we can also divide the … Read more

## Standard Form: Equation, Definition, and Examples

The standard form is referred to as the general method of representing any type of notation. A standard form formula represents the commonly accepted form of an equation, which is the standard form. As an example – The standard form of a polynomial is to write the terms with the highest degree first (descending order … Read more

## How to Find the Range of a Function? Most Simple Ways

How to Find the Range of a Function? Mathematical functions can be compared to vending machines. They give back some cookies or cans in exchange for the money they receive. Similarly, functions take numbers as inputs and return results as outputs. The reality is that everything in real life can be formulated and solved with the … Read more
