Question $3$

Let $x$ be a numeric vector. Create a new vector $y$ which consists of all entries of $x$ between $-3$ and $3($including $-3$ and $3),$ in order of appearance as in the vector $x.$ For example, if

$x=c(-5,7,0,3,14,9,5,10,-2,0,12)$

then, printing $y$ should read

$y$

$[1]0,3,-2,0$

Similarly to the previous problem, we create a function extract $()$ within which you need to type $y$ in terms of $x,$ so that for various vectors $x$ the output extract $(x)$ always gives the entries of
