What is the range of (f(x)={x}), where ({x}) is the fractional part?

Answer and explanation

Correct answer: 0 ≤ y < 1

The governing concept is the fractional-part function. For every real number x, its fractional part is defined by {x}=x−⌊x⌋, where ⌊x⌋ is the greatest integer not exceeding x. Consequently, 0≤{x}<1. The value 0 occurs whenever x is an integer, while 1 is never reached because the integer portion would then increase by one. Therefore the range is [0,1), represented by 0≤y<1, so option A is correct. Option B excludes the attainable value 0 and includes the impossible value 1. Option C confuses fractional values with integers, and option D is too broad because values greater than or equal to 1 cannot occur.
