Quadratic Functions

Certain functions are symmetric in nature and quadratic function is one of them. If you remember from earlier lessons, we classified the functions as even and odd which means even functions are symmetric over y-axis and odd functions are symmetric over x-axis in a 2d coordinate plane. What is a quadratic function ? A quadratic …

Polynomial Functions

In this article, you will learn about a special function called polynomial function. You can think of polynomials as an expression made of variables, exponents, and constants. Here the number of terms are important, hence, the name “Poly” which means “many” and “nomial” means “terms”. Standard Form The standard form of polynomial function is in …

Complex Numbers

Complex numbers are extended number system. The motivation behind complex number is that there is no solution to negative roots. Consider the equation , there is no that can satisfy this equation. Powers Of Imaginary Number i Therefore, the imaginary number is introduced as the solution to . Now, it is possible to find square …

Inverse Functions

In the previous article, you learned about composite function, in this article, you will learn about inverse functions. The term “inverse” means to “undo” something and which is what the “inverse” of a function do. If a function find the value for an value, the inverse of the function does the opposite, meaning it finds …

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 …
