Circled questions. Thank you.

ative and Connected Approach * Exploration 2.4.2: Using Matrices to Model Functions and Relations 1 . How many data points does one need in order to use matrices to find an equa- tion for a parabola of the form: y = ax + bx+ c ? 2. Recalling that [C] = [A" ] [B], explain why this matrix method will help find the desired equation. 3 How many points does one need to use matrices to find an equation for a circle of the form: 0 = x2 + y2 + Dx + Ey+F? 4 Is the above situation a function or a relation? Why? 5 Find the equation for a circle containing the points: (0, 0), (0, 5), (3, 3). 6. Find the equation for a circle containing the points: (-1, - 3), (- 2, 4), (2, 1). 7. Find the equation for a parabola containing the points: (0, 0), (20, 47), (30, 88). 8. Find the equation for a parabola containing the points: (0, 1.60), (10, 1.85), (20, 2.00). 9. Lastly, put all equations found above into standard form
