Avery collects data about the value of a collectible baseball card over time. The table shows the card’s value y, in dollars, after x years. The quadratic function f(x) = 3x2 − 7x + 10 models the relationship of the data. Calculate the residuals for the data. Drag the numbers to complete the table. Numbers may be used once, more than once, or not at all.

Step-by-step explanation: 3

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

yes   because as the functions are graphed they eventually will intersect unless otherwise
