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
xmin =-1, xmax =3, ymin =-1 ymax =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 Xmin =...................Xmax = ..................
xscl ................................ymax =...........................yscl =..........
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
