For this case we have given two functions, f (x) and g (x).

So:


(f-g) (x) = f (x) -g (x)

We have:


f (x) = 2x-6\\g (x) = 3x + 9

So:


(f-g) (x) = 2x-6- (3x + 9)

Taking into account that
- * + = -


(f-g) (x) = 2x-6-3x-9

Different signs are subtracted and the sign of the major is placed.


(f-g) (x) = - x-15

Answer:


(f-g) (x) = - x-15

Option D
