For the polynomial regression model: Select one: A. the techniques for estimation and inference developed for multiple regression can be applied. B. the critical values from the normal distribution have to be changed to 1.962, 1.963, etc. C. you need new estimation techniques since the OLS assumptions do not apply any longer. D. you can still use OLS estimation techniques, but the t-statistics do not have an asymptotic normal distribution.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

3 is greater then both of those numbers

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
