Given the function y= {3x+1 if x≥0,x−2 if x<0 }. Find its values for x=−1; 0; 1; 2. If x = −1, then y = . If x = 0, then y = . If x = 1, then y = . If x = 2, then y = .

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b.the means of the data sets are within 3 units from eachother. c.the data sets have the same standard deviation. d.the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.

Pls! does anybody know a shortcut for answering these types of questions in the future?
