domain of f(x)=(2x+4)/(x-5)

domain

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

x < 5 or x > 5

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 5

The function domain

x < 5 or x > 5

- \frac{x + 5}{x - 6}

\frac{250}{1 + e ^{- 2 x}}

f (x) = (x^{2} + 2)^{2} + 1

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

f (x) = 2 e^{x} - x^{2}

What is the domain of f(x)=(2x+4)/(x-5) ?
The domain of f(x)=(2x+4)/(x-5) is x<5\lor x>5
