Look at this set of ordered pairs: (9,8)
(12, 15)
(5, 7)
(4,9)
Is this relation a function?
yes
no

Yes, the given relation is a function.

Step-by-step explanation:

As given,

(4, 9)

(5, 7)

(9, 8)

(12, 15)

x                          y

4                          9

5                          7

9                          8

12                         15

As each input has different and unique output values.

So, the given relation is a function.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
