Determine whether the following table could represent a linear function. If it can, find a possible formula for the linear function in $y=mx+b$ form. If it can't, please write "NONE" in the formula line.

a)

$x$	$-5$	$-3$	$0$	$5$
$g(x)$	$-41$	$-21$	$9$	$59$

? Yes, this table represents a linear function No, this table does not represent a linear function
Formula: $f(x)=$

b)

$x$	$-5$	$-3$	$0$	$5$
$f(x)$	$32$	$23$	$2$	$-25$

? Yes, this table represents a linear function No, this table does not represent a linear function
Formula: $g(x)=$

Hint:
