range of f(x)=(5x+2)/(x-3)

range

f (x) = \frac{5 x + 2}{x - 3}

f (x) < 5 or f (x) > 5

Interval Notation

(- \infty, 5) \cup (5, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{5 x + 2}{x - 3}

Inverse of

\frac{5 x + 2}{x - 3} : \frac{2 + 3 x}{x - 5}

\frac{2 + 3 x}{x - 5}

Find the domain of each inverse function

Domain of

\frac{2 + 3 x}{x - 5} : x < 5 or x > 5

Combine the intervals

f (x) < 5 or f (x) > 5

What is the range of f(x)=(5x+2)/(x-3) ?
The range of f(x)=(5x+2)/(x-3) is f(x)<5\lor f(x)>5
