Answer 1

Answer:

D

Step-by-step explanation:

Just take x and replace it by 0 to see if you get 12

you will get 11.93 wich is close to 12

Answer 2

A regression can either be linear, nonlinear or no relationship at all

The equation of the quadratic regression is $y = -0.89x^2 +3.24x +11.93$

To determine the equation of the quadratic regression, we make use of a graphing calculator.

From the graphing calculator, we have the following calculator summary

• a = -0.89
• b = 3.24
• c = 11.93

A quadratic regression equation is represented as

$y = ax^2 + bx + c$

So, we have:

$y = -0.89x^2 +3.24x +11.93$

Hence, the equation of the quadratic regression is $y = -0.89x^2 +3.24x +11.93$
