range of (3x-1)/(x+2)

range

\frac{3 x - 1}{x + 2}

f (x) < 3 or f (x) > 3

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{3 x - 1}{x + 2}

Inverse of

\frac{3 x - 1}{x + 2} : \frac{- 1 - 2 x}{x - 3}

\frac{- 1 - 2 x}{x - 3}

Find the domain of each inverse function

Domain of

\frac{- 1 - 2 x}{x - 3} : x < 3 or x > 3

Combine the intervals

f (x) < 3 or f (x) > 3

What is the range of (3x-1)/(x+2) ?
The range of (3x-1)/(x+2) is f(x)<3\lor f(x)>3
