Graphing Activity 3A

(10 POINTS)

(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, 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

Ans: ……………………………………………….

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=……………….X max=

xscl…………………………..ymax=………………………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

Ans……………………………………………………
