   functions CONSTANT FUNCTION: A constant function is that function that always takes the same image for any value of the independent variable (x), that is, a constant function is of the form f(x)=k, where k is any real number. Characteristics • It is a continuous and even function, because the function always takes the same value. • The constant function is neither increasing nor decreasing, it is a type of function that always has zero slope. • The limit of the constant function as x approaches plus infinity or minus infinity is equal to the value of the constant. Domain and range: For a constant function, the domain can be any set of real numbers. The range is simply the constant value of the function. In the example above, the domain is all real numbers, and the range is {3}. Name of Graph: The graph of a constant function is a horizontal line that passes through the constant value on the y-axis. Cuts in axes: The constant function does not have cuts in...
