Question

got a long one f(x) = x+5 and g(x) = x+8 find the following (f+g)(x) then (f-g)(x) and then (fg)(x) last one f/g)(x)

Answer 1

(f+g)(x)=f(x)+g(x)
similar for (f-g)(x)
(fg)(x)=f(x)g(x)
(f/g)(x)=f(x)/g(x)

Answer 2

? thats not the answers?

Answer 3

u r to substitute the values only

Answer 4

do u know how to do it?

Answer 5

no? Im stuck I keep getting different answers

Answer 6

ok
(f+g)(x)=f(x)+g(x)=x+5+x+8=2x+13

Answer 7

got it?

Answer 8

ah ok

Answer 9

can u do the rest?

Answer 10

I can do the next step,,, how would I do the (fg)(x) one?

Answer 11

(fg)(x)=f(x)g(x)=(x+5)(x+8)=x^2+13x+40

Answer 12

the (f-g) would be 2x-3 for the answer right?

Answer 13

it would be -3 only, x is cancelled out

Answer 14

oh..crap k

Answer 15

did u get the product ?

Answer 16

last one would be x+5/x+8

Answer 17

right

Answer 18

sweet ... think I get it now thank you :)

Answer 19

:)
