To explain: The error in statement that claims a quadratic function can be drawn passing through three given points.
There is no parabola passes through points
Given data: The graph of quadratic function passes through points
Method/Formula used:
The standard equation of a quadric function is
Explanation:
If points
Let the equation of the parabola passing through the points
Substitute
OR
Substitute
OR
Substitute
OR
Comparing equations (2) and (4),
That system of equations gives
Hence, no a , b , c can be found for the points for the points
