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

range

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

f (x) < 1 or f (x) > 1

Interval Notation

(- \infty, 1) \cup (1, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

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

Inverse of

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

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

Find the domain of each inverse function

Domain of

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

Combine the intervals

f (x) < 1 or f (x) > 1

r an g e f (x) = - 2 x + 3 - 1

in v erse 2 + x + 3

d o main \frac{x ^{2} - 16}{x + 4}

sy mm e t ry y^{2} - 4 y - 6 x - 5 = 0

in v erse f (x) = \frac{3}{x ^{2} + 2 x}

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