X 2 4 8 10 16<br> Y12 45<br> 09<br> Oy= 2 x<br> Oy=1 x<br> O y=x-1<br> Oy=x+2
MrRa [10]

Answer:

<em>y = x ÷ 2</em>

Step-by-step explanation:

We are given a table of values, which will be represented as ordered pairs (x,y) below:

(2,1) (4,2) (8,4) (10,5) (16,8)

We are required to select one of the functions that match the numeric relationship between x and y.

We could test them one by one, but at simple observation, we can note the values of y are half of the values of x:

2/2=1

4/2=2

And so on. Thus the only function that divides the value of x by 2 to find the value of y is:

y = x ÷ 2
