Answer 1

This does not represent a function

`-2\leq x\leq2\\-3\leq y\leq2`

Explanation:

Function : A function defines a relationship between independent variable and dependent variable. There can't be two dependent variable corresponding to one independent variable.

here for
`x=-1,f(x)` can be any value between
`-3\ and\ 3`.

Hence this does not represent a function.

`-2\leq x\leq2\\-3\leq y\leq3`
