Lab 01
Name:
Start time: border="0" Number of questions: 9
 
This set of questions goes with the pages of applets and activities for Lab 01.  Use the applets and activities to answer the questions.
 

Question 1  (1 point)
Refer to lab page 2. Plot the points P1=(1,3) and P2=(3,7). Report the value of the slope m.

 


Question 2  (1 point)
Refer to lab page 2. Suppose P1 is a point in Q II and P2 is a point in Q IV. What can you conclude about the value of m?

 


Question 3  (1 point)
Refer to lab page 2. What happens to the value of m when P1 and P2 have different x coordinates but the same y coordinate? (You can drag the points with your mouse to experiment.)

 


Question 4  (1 point)
Refer to lab page 3. Pick f(x) number 4 and enter a linear function that matches it. What is the magic word?

 


Question 5  (1 point)
Refer to lab page 3. Pick f(x) number 3 and enter a linear function that matches it. What is the magic word?

 


Question 6  (1 point)
Refer to lab page 3. Notice the control to the left of the grapher that looks like this:
zoomer
What effect does it have on the graph that is displayed?

 


Question 7  (1 point)
Refer to the graphing utility on lab page 4. Graph equation and report on its symmetry. (Observe the symmetry both on the grapher and in the table.)

 


Question 8  (1 point)
Refer to lab page 4. Suppose equation. Use the table part of the utility to find the value reported for f(Pi/2).


 


Question 9  (2 points)
