1. a. f(x) = x2

x =                                    y = x2                                         (x,y)

-3                                   (-3)2 = 9                                       (-3,9)

-1                                   (-1)2 = 1                                       (-1,1)

0                                    0^2 = 0                                         (0,0)

1                                    1^2 = 1                                         (1,1)

3                                    3^2 = 9                                         (3,9)

b. f(x) = (x - 1)^2

x =                              y = (x-1)^2                                      (x,y)

-3                             (-3-1)^2  = 16                                   (-3,16)

-1                             (-1-1)^2 = 4                                      (-1,4)

0                              (0-1)^2 = 1                                         (0,1)

1                              (1-1)^2 = 0                                         (1,0)

3                              (3-1)^2 = 4                                         (3,4)

c. f(x) = (x-2)^2
