2. in two or more complete sentences describe why the range of y = cos(x) is -1 ≤ y ≤ 1. make sure to reference the unit circle in your description.

7. print out the graph paper from the "let's review" section. sketch the graph of y = 2tanx for -pi/2 ≤ x ≤ pi/2 and turn it into your teacher. indicate the asymptotes, if any.

in the box below, describe similarities and differences between the graphs of y = 2tanx and y = tanx.

Find the greatest common factor of the followig monomials 21u^5v,3u^4v^6, and 3u^2v^5

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
