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

domain

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

t < - 1 or t > - 1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

t = - 1

The function domain

t < - 1 or t > - 1

\frac{x - 7}{3}

\frac{x ^{2}}{x - 2}

f (x) = 9 x^{3} - 3 x

1 - (\frac{1}{2}) + (\frac{1}{3}) - (\frac{1}{4}) + (\frac{1}{5})

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