What is the domain of the function
f(t) = 1/((1 - t)^2 - (1 + t)^2)?
Express your answer in interval notation.
1
________________ =
(1 - t)^2 - ( 1 + t)^2
_________________________ =
(1 - 2t + t^2) - ( 1 + 2t + t^2)
_________________ ( the denominator cannot = 0...... so t cannot equal 0 )
- 4t
Domain = (-inf , 0) U ( 0 , inf)
