Graphing Activity

(For an example similar to #2, see #10 and #11 on page 196

1 a) Graph y₁ =¦x-1¦-0.5 on the calculator. Use the following viewing rectangle

x_min =-1, x_max =3, y_min =-1 y_max =2

b. Draw the graph labelling the horizontal intercepts

c. use the graph in the 1b to solve ¦ x-1¦-0.5 ≥ 0

2a) Graph y₂ = (1/2)x + 5 and Y₁ ¦x-1¦-0.5 on the same axes showing all points of the intersection. An appropriate viewing rectangle is X_min =...................X_max = ..................

x_scl ................................y_max =...........................y_scl =..........

2b) Draw the graph labelling all the points of intersection

C, Use the graph in part 2b to solve ¦x-1¦-0.5≤ (1/2)x+5
