The domain is all real numbers except $t\ne0$.

Work Step by Step

Any restriction on domain will occur when a value of $t$ creates a zero in the denominator. If $t=0$ and the value $0$ is substituted into the expression in the denominator, you will have a $0$ in the denominator and an undefined fraction. The domain is all real numbers except $t\ne0$.
