The function is defined for all $t$ $t$ which is $t + 2 > 0 \Rightarrow t > - 2$ $t+2>0=>t> -2$

Hence $D_{f} = (- 2, + \infty)$ $D_f=(-2,+oo)$

The range is all of $R$ $R$ or $(- \infty, + \infty)$ $(-oo,+oo)$

Graphing a function is a great way to confirm or gain insight into the domain and range of a function.
