Question

Write domain and range of greatest integer function​

Answer 1

DOMAIN ={ all real numbers} , since the co-ordinates of the X-axis can be +ive , -ive or be in fractions .

RANGE ={ 1 , 0 , -1} ,( because when ever we take the value of any real no. say , X to be 0 , we always get the G.I.F as 0. Similarly when X<0 , the G.I.F is always -1 and when X>0 the G.I.F is always 1.)

The domain of the greatest integer function is the set R of all real numbers and the range is the set Z of all integers as it attains only integer values.
