is that x/x^2 ???
or just x^2 ??
x divided by x^2 -3x +2
look differentiate it ..... find the min value ..... then decide the range appropriately
factorize denominator and find when bottom expression equals "0"

Here denominator must not be equal to zero..
sorry decide the domain appropriately
\[x^2 - 3x + 2 \ne 0\] Here find the x values..
Can you factorize it??
no differentiate it ... then put it equal to zero to find min or max value

that's how you can find the domain!!!
and yup .. we can also do it with factorization
\[(x-2)(x-1) \ne 0\] Find x from here..
