Definition and graph of Constant Function | Theory of Functions | Math Lessons

In this video we have studied the definition and graph of Constant Function. a constant function is a function whose values do not vary and thus are constant. For example the function f(x) = 5 is constant since f maps any value to 5. More formally, a function f : A → B is a constant function if f(x) = f(y) for all x and y in A.
