hey look.............

everybody...............

if u r saying that range is

from 0 to infinity........................

i think so it is wrong ..................absolutely wrong................

because............lets find 0.2 in the range.................

for this lets put it in the function...............

we get..............

y= 0.2 * 0 ( 0 is greatest integer of 0.2)

y=0..........

so............there cant be any value from (0,1)..................

in the range...............u can check it............

similarly there r many values that will not lie in the range......................

lets find 2.82...............

put x= 2.82 in function./............

we get y= 2.82* 2 =5.64...........

or take the underroot of 2.82..................

then.............

y= sqrt 2.82* 1 .............. ( 1 is greatest integer of sqrt 2.82)

= sqrt 2.82...............

so there is no particular value 4 its range ................

i think so.............

i m not against anybody ...............but please think abt it................

sorry ......if i m wrong.................

thanku
