range of f(x)=(x-4)/(3x+5)

range

f (x) = \frac{x - 4}{3 x + 5}

f (x) < \frac{1}{3} or f (x) > \frac{1}{3}

Interval Notation

(- \infty, \frac{1}{3}) \cup (\frac{1}{3}, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{x - 4}{3 x + 5}

Inverse of

\frac{x - 4}{3 x + 5} : \frac{- 4 - 5 x}{3 x - 1}

\frac{- 4 - 5 x}{3 x - 1}

Find the domain of each inverse function

Domain of

\frac{- 4 - 5 x}{3 x - 1} : x < \frac{1}{3} or x > \frac{1}{3}

Combine the intervals

f (x) < \frac{1}{3} or f (x) > \frac{1}{3}

cos (4 x)

f (x) = 4 - 5 x

- 16 t^{2} + 1700

(5, 0), (1, - 1)

\frac{5 x + 20}{x ^{2} + x - 12}

What is the range of f(x)=(x-4)/(3x+5) ?
The range of f(x)=(x-4)/(3x+5) is f(x)< 1/3 \lor f(x)> 1/3
