A quadratic function has an axis of symmetry at x=4 and contains the points (2, -6) and (7, -11). Find the equation in standard form (y=ax2+bx+c). Then state the "a" value in the equation.
Answers: 3
. The "a" value is -1.
(1)
- Parabola constant, dimensionless.
- Independent variable, dimensionless.
- Depedent variable, dimensionless.
, 
- Coordinates of the vertex of the parabola, dimensionless. 
, 
and 
, then we have the following system of linear equations:
