1) which kind of function best models the set of data points (-1,22), (0, 6), (1, -10), (2,-26), and (3, -42)?

a) linear
b) quadratic
c) exponential
d) none of the above

2) which kind of function best models the set of data points (-3, 18), (-2,6), (-1, 2), (0, 11), and (1, 27)

a) linear
b) quadratic
c) exponential
d) none of the above

3) what function can be used to model data pairs that have a common ratio

a) linear
b) quadratic
c) exponential
d) none of the above

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

i dont know

step-by-step explanation:

the reason i dont know is because i have not taken this class and for that reason i haven't learned this stuff

hope i could
