range of (6x-6)/(x+2)

range

\frac{6 x - 6}{x + 2}

f (x) < 6 or f (x) > 6

Interval Notation

(- \infty, 6) \cup (6, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{6 x - 6}{x + 2}

Inverse of

\frac{6 x - 6}{x + 2} : \frac{- 6 - 2 x}{x - 6}

\frac{- 6 - 2 x}{x - 6}

Find the domain of each inverse function

Domain of

\frac{- 6 - 2 x}{x - 6} : x < 6 or x > 6

Combine the intervals

f (x) < 6 or f (x) > 6

What is the range of (6x-6)/(x+2) ?
The range of (6x-6)/(x+2) is f(x)<6\lor f(x)>6
