Answer:
The equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is .
Step-by-step explanation:
A quadratic function is a second order polynomial of the form:
(1)
Where:
- Independent variable.
- Dependent variable.
, , - Coefficients.
From Algebra we understand that a second order polynomial is determined by knowing three distinct points. If we know that , and , then we construct the following system of linear equations:
(2)
(3)
(4)
By algebraic means, the solution of the system is:
, ,
Therefore, the equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is .
