ASAP Make a scatter plot of the data below.
Use the quadratic regression feature of a graphing calculator to find a quadratic model. Round to the nearest thousdandths place.
a. y = 7.821x2 - 0.936x - 94.034
b. y = -7.821x2 +0.936x - 94.034
y = 0.008x2 + 0.518x + 131.886
d. y = 0.008x2 - 0.518x - 131.886
C. y = 0.008x - 0.518x + 131.886
D. y = 0.008x2 - 0.518 - 131.886
