<prompt> Kazi fx x-2 kama x 4 sqrtx kama x 4. ina inverse f-1. kupata thamani ya f-1-5 f-1-4 ... f-14 f-15.  <response>: Tutaanza kwa kuzingatia mbalimbali ya kila sehemu ya fx. hebu gx x-2 kwa x 4 na hx sqrtx kwa x 4. kwa x 4, tuna x - 2 2, hivyo mbalimbali ya g ni muda -, -2. kwa x 4, tuna sqrtx 2, hivyo mbalimbali ya h ni 2, . kinyume cha g ni g-1x x 2, wakati kinyume cha h ni h-1x x2. ili kuhesabu f-1x, ni lazima kutumia g-1 kama x 2 na kutumia h-1 kama x 2: f-1 5 f-1 4... f-14 f-15 g-15 f-1 5 f-1 f-11 4 h-1 h-12 h-4 h-4 h-1 h-4 h-1 h-4 h-4 h-4 h-1 h-4 h-4 h-4 h-4 h-4 h-4 h-4 h h-1 h-4 h-4 h-4 h-1 h h-1 h h-1 h h-1 h-1 h h-1 h h-1 h h-1 h h-1 h h-1 h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h h
