domain of f(x)=(x+2)/(x-4)

domain

f (x) = \frac{x + 2}{x - 4}

x < 4 or x > 4

Interval Notation

(- \infty, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

f (x) = x 9 - x

\frac{4 e ^{x}}{e ^{x} - 5}

f (x) = \frac{( - 5 x + 2 )}{4 x + 5}

y = - \frac{4}{5} x - 4

f (x) = \frac{2 x + 5}{4}

What is the domain of f(x)=(x+2)/(x-4) ?
The domain of f(x)=(x+2)/(x-4) is x<4\lor x>4
