{0, 2, 4}

{5, 7, 9}

Answer 1

@surjithayer

Answer 2

Domain =x Range = y

Answer 3

Yes, I know this. Lol

Answer 4

So for each value of x what would be the y value?

Answer 5

That's what I don't understand

Answer 6

put x=0,2,4 in x-y=5,find y for each value

Answer 7

I don't understand the x-y=5 part and how I'm supposed to find the value of y from that

Answer 8

x-y=5
if x=0
0-y=5
y=-5
similarly find other values.

Answer 9

#1

Answer 10

if x=2
2-y=5
-y=5-2
-y=3
y=-3

Answer 11

if x=4
y=?

Answer 12

???

Answer 13

4-y=5
-y=5-4
-y=1
y=-1

Answer 14

If K = {(x, y ) | x - y = 5}, is Set K a function?



Yes

No

Answer 15

yes,because for one value of x we get only one value of y.
