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

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

what is the answer?

can you make your screen more see able?

then i might be able to .
