week 3 quiz2

course mth 163

You said to resubmit this quiz with the question on it.

Make tables and sketch graphs of y = x, y = x 2 , y = x -1 and y = 2 x , for x = -3 to x = 3. - y=x: (-3,3); (-2,2); (-1,1); (0,0); (1,1); (2,2); (3,3)

- y=x^2: (-3,9); (-2,4); (-1,1); (0,0); (1,1); (2,4); (3,9)

- y=x^-1: (-3, -1/3); (-2, -.5); (-1, -1); (1,1); (2, .5); (3, 1/3)

- y=2^x: (-3, .125); (-2, .25); (-1, .5); (0,1); (1,2); (2,4); (3,8)

Good.

You should also include a description of each graph (e.g., where is it increasing, where is it decreasing, in either case is it at an increasing or decreasing rate; where are its asymptotes, if any; does it pass through the x and y axes and if so where?).
