Find the maximum likelihood estimator of  . How do you know it gives a maximum?

1. Let \( X_1, X_2, \ldots, X_n \) be independent random variables from a distribution with pdf 

\[
f(x \mid \theta) = 
\begin{cases} 
(\theta + 1)x^{\theta} & \text{for } 0 < x < 1 \text{ and } \theta > -1 \\
0 & \text{elsewhere}
\end{cases}
\]

Find the maximum likelihood estimator of \( \theta \). How do you know it gives a maximum?
