Question

i need help to know how to find the domain and range for any function ???????????

Answer 1

no one answered because there is "no one answer"
it depends on the function.
the truth of the matter is that the domain is supped to be part of the definition of the function, but often it is not, and you are supposed to assume that the domain is the largest set of numbers on which the function can act

Answer 2

you would be better off giving a specific question about a specific function

Answer 3

i dont know how to solve all the function that why i need to know what domain and range first coz i dont want to get the answer for one function i need to understand it first

Answer 4

look for value of x when function is invalid, (ie, 0 in denominator)
