Constant Function
A constant function is a special type of function in mathematics where the output value remains the same for every input value
A constant function is a special type of function in mathematics where the output value remains the same for every input value. In other words, regardless of the input, the function always returns a fixed value.
Mathematically, a constant function can be defined as f(x) = c, where “c” is a real number representing the constant value. This means that for every value of x, the function f(x) will always be equal to the constant “c”.
For example, let’s consider the function f(x) = 5. This is a constant function because no matter what value of x we substitute into the function, the result will always be 5. So, f(2) = 5, f(0) = 5, f(-3) = 5, and so on.
Graphically, a constant function is represented by a horizontal line on a coordinate plane. The line is parallel to the x-axis and intersects the y-axis at the constant value.
It is important to note that a constant function does not have a variable or expression dependent on the input. It represents a situation where the output is independent of the input, and the function output remains fixed.
