<prompt> Je!fx -1floor x floor sqrtfrac14 - left x - floor x floor - frac12 kulia2 kitendakazi sawia, kitendakazi kisicho cha kawaida, au hakuna?Ingiza isiyo ya kawaida, hata, au wala.  <response>: Ikiwa x ni nambari kamili, basi x floor x floor, hivyofrac14 - kushoto x - frac12 - floor x floor kulia2 frac14 - frac1 4 0,ambayo ina maana fx 0.Vinginevyo, floor x floor x floor x floor 1, hivyo-sakafu x saka - 1 -x -floor x floor,ambayo ina maana floor -x floor -floor x floor - 1. Kwa hivyo,anzaalignf-x -1floor -x floor sqrtfrac14 - left -x - floor -x floor - frac1 2 kulia2 -1-floor x floor - 1 sqrtfrac14 - left -x floor x floor 1 - frac12 kulia2 -1-floor x floor - 1 sqrtfrac14 - left -x floor x floor frac12 kulia2 --1-floor x floor sqrtfrac14 - kushoto x - floor x floor - frac12 kulia 2 -fx.endalignKwa hivyo, fx ni textodd chaguo.Grafu ya y fx ni ifuatayo:asyukubwa wa kitengo 2.5 cm;kuchoraarc12,0,12,0,180,nyekundu;kuchoraarc32,0,12,180,360,nyekundu;kuchoraarc52,0,12,90,180,nyekundu;kuchoraarc-12,0,12,180,360,nyekundu;kuchoraarc-32,0,12,0,180,nyekundu;kuchoraarc-52,0,12,270,360,nyekundu;chora-2.5,0--2.5,0;chora0,-12--0,12;lebodots, 2.7,0;lebodots, -2.7,0;nuktafrac12,0, 12,0, S;nuktafrac32,0, 32,0, N;nukta-frac12,0, -12,0, N;nukta-frac32,0, -32,0, S;asyGrafu ina miduara iliyo katikati ya nusu nambari kamili, na radii frac12.
