MHB What is the Domain of the Function t^(-1) + 2t^(-2)?

[mathdad]

Find the domain.

t^(-1) + 2t^(-2)

Let me see if I get it.

1/t + 2/t^(2)

Let D = domain

D = t is all real numbers except for 0.

D = t is all real numbers except for 0.

yes because at t = 0 it is not defined and at all other t it is defined
