Question

i tried doing this but it seems that im doing something wrong.

Answer 1

What is the domain of f?

Answer 2

well x cannot equal 5

Answer 3

for f(x)

Answer 4

and the domain of g?

Answer 5

x cannot equal -3

Answer 6

intersect that domain with your other domain and you have the domains for all your functions you are looking for

Answer 7

what do you mean? like after i solve for them

Answer 8

ok so my question was the for (f+g)(x) you add them and so on for the other ones?

Answer 9

Oh you don't have question for domains?
just with operations?

Answer 10

(f+g)(x)
means you will add f(x) to g(x)

Answer 11

so if you had f(x)=5 and g(x)=6+x
then (f+g)(x)=5+6+x=11+x

Answer 12

ok so for the first example i would have to make them have the same denominator right?

Answer 13

Yeah

Answer 14

In order to add them you need the same denominator
