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

domain

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

f (x) = 3 + x + 3 - x

f (x) = cos (cos (x))

f (x) = - 4^{x} + 5

- 5 x + 10

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

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