ax^2 + bx + c = 0
Use appropriate values of a, b, c. State also the quadratic equation that you are using in your solution.
Answer:
3x^2 + 20x + 25
2)Contruct a tangent to the curve stated above any point.
State the equation of the tangent line in your solution.(Hint: Observe the left side panel of the Geogebra)
Answer:
3) (i) How many points of contact are there between the tangent line and the curve?
(ii) State the coordinate, (x,y) of point of contact between tangent line and the curve.
Answer:
3i) One
3ii) (-1.88,-2)
(4)It is possible to have one more than 1 point of contact between the tangent line and the curve?
If yes, state your reason and show an example.
If no, state your reason
Answer:
No, a tangent only touches one point of the curvel. Refer to the Diagram above.
(5)Presentation of solutions and appropriate use of values.
Answer:
5) Solution: a: 3
b:20
c=25
(3x+5)(x+5)
