Question

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

Answer 1

Answer: yˆ 0.0371x2 - 0.5691x - 0.341

Step-by-step explanation:

Using the quadratic regression equation calculator,

The quadratic regression equation is :

yˆ 0.0371x2 - 0.5691x - 0.341

Taking the form Ax^2 + Bx + C

A = 0.0371

B = -0.5691

C = -0.3410
