domain of f(x)= 4/(t^2-1)

domain

f (x) = \frac{4}{t ^{2} - 1}

t < - 1 or - 1 < t < 1 or t > 1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

t = 1, t = - 1

The function domain

t < - 1 or - 1 < t < 1 or t > 1

F (C) = \frac{9}{5} C + 32

f (x) = x^{2} - 6 x - 7

f (x) = - x - 2

(4, 7), (0, 3)

f (x) = \frac{3 x}{x ^{2} - 16}

What is the domain of f(x)= 4/(t^2-1) ?
The domain of f(x)= 4/(t^2-1) is t<-1\lor-1<t<1\lor t>1
