How can I check my answer?

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?

Yes, -2 does not satisfy the other two equations.

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

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

does that mean that the answer is correct?

Yes! As far as I can follow your workings.
It should be \(\displaystyle \vec{v}(0)+t~\vec{v}~'(0)\)
