to find the domain first check all the possibilities of the denominator attaining a value of zero then if the function has any thing inside a square root, the expression inside the root must be always greater than or equal to zero.If the square root is in the denominator then the expression inside must be just greater than zero but not equal to zero.

How do you find the domain if you are given the range?

Use the function to find the image of each point in the domain. The set of values that you get will be the range. If the function is well behaved, you will not have to try each and every value in the domain.


If a function is defined by an equation explain how to find its domain.?

The set of all values of x, for which the equation is true is the domain of the function defined by that equation.


What is the Domain of the sin function?

The domain of the sine function is all real numbers.


How does the domain relate to a function?

Any function is a mapping from a domain to a codomain or range. Each element of the domain is mapped on to a unique element in the range by the function.


How do you sketch a piece wise continuous function?

A piece-wise continuous function is one which has a domain that is broken up inot sub-domains. Over each sub-domain the function is continuous but at the end of the domain one of the following possibilities can occur:the domain itself is discontinuous (disjoint domains),the value of the function is not defined at the start or end-point of the domain ((a hole),the value of the function at the end point of a sub-domain is different to its value at the start of the next sub-domain (a step-discontinuity).A piece-wise continuous function is one which has a domain that is broken up inot sub-domains.

How can you find the domain and range of a function?

The domain is a subset of the values for which the function is defined. The range is the set of values that the function takes as the argument of the function takes all the values in the domain.

How do you find the range for a function?

The range of a function is the set of all of the possible values that it can take on as an output value. You find the range by inspecting the function and seeing first what the domain is, and then what the range would be for that domain. The domain, then, is the set of all of the possible values that it can take on as an input value.


How do you find the range with the domain?

Find the range of a function by substituting the highest domain possible and the lowest domain possible into the function. There, you will find the highest and lowest range. Then, you should check all the possible cases in the function where a number could be divided by 0 or a negative number could be square rooted. Remove these numbers from the range. A good way to check to see if you have the correct range is to graph the function (within the domain, of course).
