Question

quadratic function is a function of the form y=ax²+bx+c where a, b, and c are constants. Given any 3 points in the plane, there is exactly one quadratic function whose graph contains these points.

Find the quadratic function whose graph contains the points (5, 45), (−3, 5), and (0, 5).

Enter the equation below.

Answer 1

put all 3 points (5, 45), (−3, 5), and (0, 5).

.

so 3 equations are

.

system Ax=b is

augmented matrix is

.

solution is

.

quadratic function is
