domain of f(x)= 9/(x-2)

domain

f (x) = \frac{9}{x - 2}

x < 2 or x > 2

Interval Notation

(- \infty, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2

The function domain

x < 2 or x > 2

f (x) = (x - 5)^{2} - 1

y = \frac{1}{t ^{2}} cos^{2} (t)

f (x) = (x^{2} - 3)^{2} (x^{2} + 3)^{2} = 0

f (x) = (x + 7)^{2}

\frac{3 x + 27}{x ^{2} + 6 x}

What is the domain of f(x)= 9/(x-2) ?
The domain of f(x)= 9/(x-2) is x<2\lor x>2
