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

domain

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

- \infty < t < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < t < \infty

f (x) = 3 sin (x + π)

f (x) = \frac{1}{- 3 x ^{2} - 30 x - 48}

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

y = - 3 cos (x)

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

What is the domain of f(t)= 1/((t-1)^2+(t+1)^2) ?
The domain of f(t)= 1/((t-1)^2+(t+1)^2) is -infinity <t<infinity
