find the domain of the following function given by f(x) = x/x^2 -3x +2.

OpenStudy (anonymous):

is that x/x^2 ???

OpenStudy (anonymous):

or just x^2 ??

OpenStudy (anonymous):

x divided by x^2 -3x +2

OpenStudy (anonymous):

look differentiate it ..... find the min value ..... then decide the range appropriately

OpenStudy (anonymous):

factorize denominator and find when bottom expression equals "0"

OpenStudy (anonymous):

Here denominator must not be equal to zero..

OpenStudy (anonymous):

sorry decide the domain appropriately

OpenStudy (anonymous):

\[x^2 - 3x + 2 \ne 0\] Here find the x values..

OpenStudy (anonymous):

Can you factorize it??

OpenStudy (anonymous):

no differentiate it ... then put it equal to zero to find min or max value

OpenStudy (anonymous):

that's how you can find the domain!!!

OpenStudy (anonymous):

and yup .. we can also do it with factorization

OpenStudy (anonymous):

\[(x-2)(x-1) \ne 0\] Find x from here..
