Dear Student ,

Please find below the solution to the asked query :

fx=xx2-3x+2We know value in denominator can't be zero and value under square root should be greater than or equal to zero
So, for fx to be definedx2-3x+2 > 0x2-2x -x +2 >0x x-2 -1 x-2 >0x-2 x-1 > 0⇒x<1 , x > 2So,Domain= -∞ , 1 ∪ 2 , ∞
