Part 3
Question 1
A. What is the formula for the circle (given in the Conic section to the left of the graph?) B. What is the center of the circle?
Question 2
What is different about the formula and the center of the this circle from that of the circle in the question 1? (Hint: what happened to the signs?)
Question 3
A. What is the formula for the circle? B. What is the center of the circle?
Question 4
What happened when you made slider 'k' negative? What effect did this change have on the formula and center of the circle?
Question 5
A. Using variables, what are the general coordinates of the center of the circle? B. Based on the pattern you discovered, what is the general formula for a circle?
Graph A
Center: (2, -3) Radius: 4
Graph B
If h=1, k=5, and r=2, what is the... A. Center: B. Radius: C. Equation:
Graph C
Center: (-5, 4) Radius: (sqrt(3))
Question 6
Do I have to have a graph to be able to answer the above questions about Graphs A, B, and C? Why or why not?
