Question

Picture coming...

Answer 1

i think its asking you ros and sor at x=4 right??

Answer 2

Yes, I believe so.. but when I try I can't work it out.. I come up with -30=/=-8

Answer 3

(ros)(4)=r(s(4))=r(-30)=+60
(sor)(4)=s(r(4))=s(-8)=-126

Answer 4

so.. when plugging in r.. would I first solve for r if x=4 or would I just plug the whole equation in?

Answer 5

first solve x=4 it means put 4 instate of x in equation and solve

Answer 6

Ok, so I come up with r=-1/2 then I would solve the same for s and use those values in r(s(4))=r(-30)=+60?

Answer 7

no i think ur doing wrong cause if u put 4 in equation r(x) u will come up with -8 NOT WITH -1/2 and if u put -8 in equation s(x) u will come up with -126

Answer 8

Shoot... I must be because I came up with r=-1/2 and s=-3/2 >.<

Answer 9

do it again u will get my answer i think

Answer 10

OOOHHH Yes... I see what I did wrong

Answer 11

Ok, I think I got it now.. would you mind checking my final answer as soon as I get it? :/

Answer 12

no problem what u got the final answer?

Answer 13

the final answer will be what i got that and post that for you

Answer 14

Ok... so would ros=-126 then? I guess I don't get it after all >.<

Answer 15

ros(4) rather

Answer 16

(ros)(4)=+60 NOT -126

Answer 17

Oh.. so i got them backward then

Answer 18

I get it! Ok, so basically, I evaluate the s(x) function for x=4, I take that answer (-30) and plug it into r(x) to come up with 60

Answer 19

Thank you very much Roh!! I greatly appreciate it, I wish I could give you more than one medal!

Answer 20
