Question

i dont understand funtions please help
Which ordered pairs in the form of (x,y) does not represent a funtion of x? (-1,2),(3,2),(0,1),(5,2)
(-1,2),(3,2)(-2,2),(0,2)
(1,2),(3,2),(0,1),(3,5) and (-1,2),(2,3),(3,-2),(-2,0)

Answer 1

what kind of functions?

Answer 2

(-1,2),(3,2),(0,1),(5,2)
-1,2/3,2/-2,2/0,2
1,2/3,2/0,1/3,5 and -1,2/2,3/3,-2/-2,0

Answer 3

can you explain how i would solve this

Answer 4

I don't understand ur question

Answer 5

those four sets are the ordered pairs they gave me in (x,y) form im to find which set does not represent a function of x

Answer 6

(-1,2),(3,2),(0,1),(5,2)
(-1,2),(3,2)(-2,2),(0,2)
(1,2),(3,2),(0,1),(3,5) and (-1,2),(2,3),(3,-2),(-2,0)

Answer 7

Answer 15

thanks @Mehek14

Answer 16

Look for sets of points that have repeated x values to find the non-function.

Example:

{ (5,7), (5,8), (10,19), (12,27) }

The x coordinate x = 5 pops up more than once, so this relation isn't a function.

Answer 17

so to find the answer for my question i would only have to find the x the repeats?

Answer 18

yes

Answer 19

so c would be the answer?

Answer 20

(1,2),(3,2),(0,1),(3,5) this one?

Answer 21

yep it's (1,2),(3,2),(0,1),(3,5) since x = 3 shows up twice

Answer 22

A function must produce exactly one output for any given input. With the input of 3, we ask ourselves "what is the true output? 2? or 5?". Since we don't know for sure we just say it's not a function

Answer 23

thanks so much you explain that better than my teacher could you help with a few more?
like explain them to me?

Answer 24

sure I can help
