Let \( f_{1}: R \rightarrow R, f_{2}:[0, \infty) \rightarrow R, f_{3}: R \rightarrow R \) and \( f_{4}: R \rightarrow[0, \infty) \) be defined by
\( \mathrm{P} \)
L List I
List II
P. \( f_{4} \) is
1. onto but not one-one
Q. \( f_{3} \) is
2. neither continuous nor one-one-
R. \( \quad f_{2} \mathrm{O} f_{1} \) is
3. differentiable but not one-one
S. \( f_{2} \) is
4. continuous and one-one
\begin{tabular}{rllll}
