Just subtract them. :D
THAT IS IT!! :D

Understood? :)

anonymous · Answer

so 2x-2 - x+4(x)?

akashdeepdeb · Answer

Haha.. No that x is not multiplied to it..
It is the result of another function...
(f-g)(x) [IS ONE FUNCTION like f(x) and g(x)]

So just subtract 
2x-2 -x-4

Understood? :)

anonymous · Answer

that's it...just subtract them...for addition.  multiplication is different.

anonymous · Answer

I got 6 @AkashdeepDeb

akashdeepdeb · Answer

2x-2-x-4
x-6

That is it!! :D
6 is not the actual answer..
If they had said (f-g)(0)
Then the answer would have been x-6 or (0) - 6 = -6

Understood? :)

anonymous · Answer

ooooh ok so -6

akashdeepdeb · Answer

NO!! :D
The answer is x-6

Because they have said (f-g)(x)

Understood? :)
