A function can have multiple inputs. The domain of these functions is a set of tuples.

For example if there is a function

$$

:

$$

$\backslash$times

$$

$->$

$$

g:A$\backslash$times B$->$C and

$$

$($

$$

$)$

$=$

$$

f$($x$)=$y$,$ which of the following are true:

$($choose all that apply$)$

The following checkbox options contain math elements, so you may need to read them in your screen reader's $$reading$$ or $$browse$$ mode instead of $$forms$$ or $$focus$$ mode.

Choice $1$ of $6$:

$$

in

$$

x in A and

$$

in

$$

x in B

Choice $2$ of $6$:

$$

in

$$

$\backslash$times

$$

x in A$\backslash$times B

Choice $3$ of $6$:

$$

x is a pair

Choice $4$ of $6$:

$$

x is a tuple

Choice $5$ of $6$:

$$

x is a sequence

Choice $6$ of $6$:

$$

$($

$$

$)$

f$($x$)$ is a tuple
