Actually Welcome to the Concept of the Functions.

So here to get the (f-g) (x) , we do the subtraction of the two functions now,

==> 8x + 5 - (9x -2)

===> 8x + 5 -9x +2

===> 8x - 9x +7

==> -x + 7

hence the new function (f-g) (x) = 7 - x

and the domain is from (- infinite to + infinite)

$domain = ( - \infty \: to \: \infty )$
