2) Let f and g be the functions whose values at x = R are given by f(x) = 1-x², and g(x) = √√x (i) Find (g of)(x) and (fog)(x). (ii) What are the domains D(g of) and D(fog)?

I would like to know how to determine the y and x factors needed to compute a multiple regression program based on the data supplied with this request. The solution here on Bartleby has broken images and has no assistance. I have learned how to run the program in Excel however, I am not sure which columns are needed in the analysis. The question simply states - estimate the demand for soft drinks using a multiple regression program available on your computer. Help? Thanks!

question/description of problem is attached in one of the images. please complete parts C and D!!

I am having hard time solving a? I am struggling to understand this question. Can you please show me how to solve this question step by step and be very detailed about it, how you were able to do so and what you used to get these answers. My class is using the Simple linear Regression in excel method I do I used that to get the answer for this problem below? When survey data indicated that a coffee company needed to improve its​ package-sealing process, an experiment was conducted to determine the factors in the​ bag-sealing equipment that might be affecting the ease of opening the bags without tearing the inner liner of the bag. Data were collected on 19 bags and the plate gap on the​ bag-sealing equipment was used to predict the tear rating of a bag.  a. Construct a 95​% confidence interval estimate of the mean tear rating for all bags of coffee when the plate gap is 0.   _____≤μY|X=0≤______ ​(Type integers or decimals. Round to three decimal places as needed. Use ascending​ order.)
