Here you will learn what is constant function with definition, graph and examples.<\/p>\n

Let’s begin –<\/p>\n

What is Constant Function ?<\/h2>\n

Definition<\/strong> : If k is a fixed real number, then a function f(x) given by f(x) = k for all x \\(\\in\\) R is called a constant function.<\/p>\n

For Example<\/strong><\/span>, f(x) = 2 , f(x) = 5, f(x) = 2.5 etc.<\/p><\/blockquote>\n

Sometimes we also call it the constant function k.<\/p>\n

Graph of Constant Function<\/h2>\n

The graph of a constant function f(x) = k is a straight line parallel to x-axis which is above or below x-axis according as k is positive or negative.<\/p>\n

If k = 0, then the straight line is coincident to x-axis.<\/p>\n

\"constant<\/p>\n

Domain and Range<\/h2>\n

We observe that the domain of the constant function f(x) = k  is the set R of all real numbers and range of f is the singleton set {k}.<\/p>\n

Domain<\/strong> : R<\/p>\n

Range<\/strong> : {k}<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
