How to find the domain and range of a function.

The domain is usually defined for the set of real numbers that can serve as the function's input to output another real number. If you input any number less than 4, the output would be a complex number, and would not count toward the domain. The function provided in the video would be undefined for real numbers less than 4.Example 5. Find the domain and range of the following function. f (x) = 2/ (x + 1) Solution. Set the denominator equal to zero and solve for x. x + 1 = 0. = -1. Since the function is undefined when x = -1, the domain is all real numbers except -1. Similarly, the range is all real numbers except 0. Lesson 6: Determining the domain of a function. Determining whether values are in domain of function. Identifying values in the domain. Examples finding the domain of functions. Determine the domain of functions. Worked example: determining domain word problem (real numbers)For every polynomial function (such as quadratic functions for example), the domain is all real numbers. If f (x) = a (x-h)² + k , then. if the parabola is opening upwards, i.e. a > 0 , the range is y ≥ k ; if the parabola is opening downwards, i.e. a < 0 , the range is y ≤ k . To determine the domain and range of a function, first determine the set of values for which the function is defined and then determine the set of values which result from these. E.g. #f(x) = sqrtx# #f(x)# is defined #forall x>=0: f(x) in RR#
