What is the quadratic regression equation for the data set?

x : -6, -4, -2, 0, 2, 4, 6

y : 4.56, 2.84, .45, 0, -1.14, -2.1, -2.48

a) yˆ=0.032x2+0.601x−0.255

b) yˆ=0.032x2−0.601

c) yˆ=0.032x2−0.601x−0.255

d) yˆ=0.032x2−0.601x

step-by-step explanation:

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

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.

good luck on ur quiz test or homework. have a good day : )
