domain of f(x)=(x+1)/(2-x)

domain

f (x) = \frac{x + 1}{2 - x}

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) = \frac{2 x - 4}{x ^{2} + 5 x - 14}

y = 2 sec (x)

g (x) = \frac{x + 3}{2 x - 1}

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

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

What is the domain of f(x)=(x+1)/(2-x) ?
The domain of f(x)=(x+1)/(2-x) is x<2\lor x>2
