For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0....
Co-Domain– The set of all the outputs of a function is known as the range of the function or after substituting the domain, the entire set of all values possible as outcomes of the dependent variable. Range– The set of all the outputs of a function is known as the range of the fun...

Domain and Range Table Trigonometric Functions and Inverses Lesson Summary Frequently Asked Questions What is the range of a trig function? For every x-value entered into the function, a y-value is produced. The range of a trig function is all the y-values of the function. What is the ...
Domain and Range of Exponential Function We know that thedomain of a functiony = f(x) is the set of all x-values (inputs) where it can be computed and the range is the set of all y-values (outputs) of the function. From the graphs of f(x) = 2xand g(x) = (1/2)xin the...
Structure of a Function The structure of a function determines its domain and range. Some functions, such as linear functions (e.g., f(x)=2x+1f(x)=2x+1), have domains and ranges of all real numbers because any number can be input and a unique output can always be produced. On the...
A modulus function gives the magnitude of a number irrespective of its sign. It is also called the absolute value function. It is of the form f(x) = |x|. The domain of the modulus function is ℝ and its range is [0, ∞). Its graph is V-shaped.
