domain of f(x)=(2x+4)/(x-3)

domain

f (x) = \frac{2 x + 4}{x - 3}

x < 3 or x > 3

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

f (x) = \frac{- 2 x + 6}{3}

arccos (2 x) \cdot ln (x^{2})

f (x) = \frac{2}{x ^{2} + 2 x - 24}

\frac{( x ^{2} - 2 x )}{x ^{2} + x - 6}

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

What is the domain of f(x)=(2x+4)/(x-3) ?
The domain of f(x)=(2x+4)/(x-3) is x<3\lor x>3
