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

domain

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

x < 1 or x > 1

Interval Notation

(- \infty, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

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

(3.5) (- 2.8)

y = 9 x, (- 9, 7)

\frac{- 5 - 4 x}{7 x - 2}

\frac{2 + x}{x - 5}

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