How can I check my answer? can I just plug t into the final parametric equation and check if I get the same given points?

The 1st equation in which you solved for t also has the result of t=-2. Will this change anything?

2\displaystyle -2 is not in the domain of r\displaystyle \vec{r}, because log(t+1)exp(t)\displaystyle \log(t+1)-\exp(t) would not exist for t=2\displaystyle t=-2.

does that mean that the answer is correct?
