Answer 1

fog: {(2.-7)}
gof: {(1,0),(2,10)} ?

Answer 2

I'm looking at the problems. which one are you doing?

Answer 3

start number 4 now . i will send the note for lession

Answer 4

Yes. You did it correctly.

Answer 5

let start number 22

Answer 6

fog: I don't know
gof: not axit ?

Answer 7

FIrst, the domain of g is {1 -3 2} you have {1 3 2}.

Answer 8

yes
fog:{(1.-3),(2,1)} ?

Answer 9

Here's how I do it.
f o g
input x 1 -3 2
g(x) 0 1 1
f 0 1 1
f(g(x)) -3 1 1
so matching the first row with the last (1,-3), (-3,1), (2,1)

Answer 10

g o f
x 1 0
f(x) 1 -3
g 1 -3
g(f(x)) 0 1

so (1,0), (0,1)

Answer 11

ok,gof I was wrong
fog?

Answer 12

See my post up above. (1,-3), (-3,1), (2,1)

Answer 13

I don't get fog
f has 2 pair (1.1),(0.-3),2 domain
1, 0
how you get 3 domain
0 1 1 ?

Answer 14

phi I get it now,let check my next number

Answer 15

Question (22) gives g as { (1,0), (-3,1), (2,1) }

Answer 16

What's the next number?

Answer 17

24

Answer 18

f o g
x 0 8 3 -1
g(x) 4 6 6 8
f 4 6 6
f(g(x)) 0 3 3

so from the top and bottom rows we get { (0,0), (8,3), (3,3)}

Answer 19

gof {(3,8),(4,8),(6,4),(7,4)}?

Answer 20

No. Can you try to do it the way I am doing it?
first write down the domain of f
underneath write f's range
underneath write g domain where it matches f's range
underneath write g range

Answer 21

The last line is just the 2nd number in g's definition.
g is {(0,4), (8,6), (3,6), (-1,8)}
so if you if you see a 0 in the third line, see if there is a pair that starts with 0.
If there is, put the 2nd number (here it is 4) beneath the 0.
Try it.

Answer 22

gof
x 3 4 6 7
f(x) 8 0 3 -1
g o 8 3 -1
g(f(x)) 4 6 6 8

Answer 23

gof: {(3,4),(4,6),(6,6),(7,8)} ?

Answer 24

Almost.
Your third row must match the 2nd row (if you can find a match).

Answer 25

gof
x 3 4 6 7
f(x) 8 0 3 -1
g 8 0 3 -1
g(f(x)) 4 6 6 8

Answer 26

Here's what you should do. Take g= {(0,4), (8,6), (3,6), (-1,8)}
write it as
0 8 3 -1
4 6 6 8
Call this the "g" table
The top 0 goes with the bottom 4, the 8 goes with the 6, and so on.
no look at the 2nd line in your table. it starts with 8.
look for an 8 in the "g" table. If you find an 8, copy both the 8 and the number below it
so the 8 goes in the third row, and the 6 goes in the 4th row.

Answer 27

gof
x 3 4 6 7
f(x) 8 0 3 -1
g 0 8 3 -1
g(f(x)) 4 6 6 8
then odre pair is
gof {(3,4),(4,6),(6,6),(7,8)} ?

Answer 28

f is {(3,8), (4,0), (6,3), (7,-1)}
Rewrite so the 1st numbers form the first row, and the 2nd number form the 2nd row.
3 4 6 7
8 0 3 -1
now look at the "g" table:
0 8 3 -1
4 6 6 8

match the 8's
3 4 6 7
8 0 3 -1
8
6

now look for a 0 in the 1st row of the g table, and find 0 4
3 4 6 7
8 0 3 -1
8 0
6 4

Can you finish?

Answer 29

sorry I don't get it

Answer 30

3 4 6 7
8 0 3 -1
8 0 3 -1
6 4 6 8

so g o f is (3,6), (4,4), (6,6), (7,8)

Answer 31

Can you puzzle on it for a day? Maybe it will become clearer after some time.
I'll be happy to help tomorrow, but I have to go now.

Answer 32

3 4 6 7
8 0 3 -1
8 0 3 -1
6 4 6 8
