Domain is any real value except $x = -1/2$ . Range is any real value.

$f(x)= (3x-4)/(1+2x)$ . For domain denominator must not be zero.

Domain (values of x) is any real value except $1+2x = 0 or 2x = -1 or x = -1/2$

Range (values of f(x)) is any real value. graph{(3x-4)/(1+2x) [-40, 40, -20, 20]} [Ans]
