Graphical Representation of an Even Function

In the graphical representation of an even function, the curve is always symmetric about Y-axis. In other words, the value of f(x) remains constant irrespective of the sign on x (positive or negative). Few examples of graph of even functions are given below:

Even Function

Even function is defined as a function that follows the relation f(-x) equals f(x), where x is any real number. Even functions have the same range for positive and negative domain variables. Due to this, the graph of even functions is always symmetric about the Y-axis in cartesian coordinates.

In this article, we will learn about even functions, their examples, properties, graphical representation of even functions, some solved examples, and practice questions related to even functions.
