Graph fx x 1 Then state the domain and range Choose the co

Graph f(x) = [x - 1]. Then state the domain and range. Choose the correct graph. What is the domain? Choose the correct range. the set of real numbers (-infinity, infinity) the set of integers (1, infinity)

Solution

The domain of the function will be all real numbers becuase \'x\' is defind for all real values of \'x\'. (-infinity,infinity)

Graph of f(x)=[x-1] will be the graph of f(x)=[x] with shift to 1 units towards right. So correct answer is B.

Range will be set of all integrer becuase for any real value of \'x\' function will return only integer part of number (option B) is correct!
