Question

f(x) = 2x - 2
g(x) = x + 4
Find (f - g)(x) Functions Help!

Answer 1

Just subtract them. :D
THAT IS IT!! :D

Understood? :)

Answer 2

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

Answer 3

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? :)

Answer 4

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

Answer 5

I got 6 @AkashdeepDeb

Answer 6

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? :)

Answer 7

ooooh ok so -6

Answer 8

NO!! :D
The answer is x-6

Because they have said (f-g)(x)

Understood? :)

Answer 9

x-6 gotcha!
