Answer:  The answers are in the steps please look carefully.

Step-by-step explanation:

To solve for each value input the value into the function and solve to find f(x)

A. f(-3) = 2(-3)^2 + 2

   f(-3)  = 2(9) + 2

    f(-3) = 18 + 2  

    f(-3) = 20

B.      f(6) = 2(6)^2 + 2

        f(6) = 2(36) + 2

        f(6) = 72+ 2

        f(6) = 74

C.      f(-1) = 2(-1)^2 + 2

        f(-1) = 2(1)  + 2

        f(-1)=  2 + 2

        f(-1) = 4

D.     f(4) = 2(4)^2 + 2

       f(4) = 2(16)  + 2

       f(4) = 32 + 2

       f(4) = 34

Surveys conducted in American high schools concluded that 90% of the students in a sample of 400 students had more than one acti

The sample proportion has an approximately normal distribution, with the mean being the population mean and the standard deviation (i.e. the standard error of the sampling proportion) equal to 

SE = sqrt(p*q/n) where p is the population proportion q is 1-p, and n is the sample size. 

<span>(Typically, for a confkdence interval, the sample proportion and its complement are substituted for p and q.) </span>

The margin of error will be Zc*SE, where Zc is the critical value of Z for the level of confidence required. The confidence interval, then, will be the sample proportion, plus or minus the margin of error. 

For a 90% confidence interval, Zc is 1.645. 

<span>So the margin of error is 1.645 * sqrt(.9*.1/400), roughly .025. So your confidence interval would be around [.875, .925] 


The best and most correct answer among the choices provided by your question is the second choice or letter C which is 3%.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span>
