Which quadratic regression equation best fits the data set?

x y
0 31
1 29
2 28
4 22
6 19
10 11
11 8

answers:

yˆ=31.179x^2+2.051x−0.002

yˆ=−0.002x^2−2.051x−31.179

yˆ=−0.002x^2−2.051x+31.179

yˆ=31.179x^2−2.051x−0.002

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
