Question

How do you find the domain and range of `f(x)= (3x-4) / (1+2x)`?

Answer 1

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

Explanation:

`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]
