The function c combines the numbers in its argument into a vector, which in this case is assigned to $x$

\n

a)

\n

The function mean returns, as expected, the mean of the values in its argument.

\n

b)

\n

The function range returns a vector containing the minimum and maximum of its argument, in this case the minimum and maximum of $x$, so $1$ and $6$. In fact we could have answered this without any further information; this was the only possible answer, as we expected a vector with 2 elements.
