Question 1153438: x −2 −1 0 1 2
y 9 4 1 0 1
Use the table of values that represent points on the graph of a quadratic function. By determining the vertex and axis of symmetry, find the general form of the equation of the quadratic function.
y =

..........use given and values to calculate coefficients , , and constant
............eq.1
............eq.2
............eq.3
go to
............eq.1, plug in
............solve for
..........1a
go to
............eq.2, plug in
...........solve for
..........2a
from 1a and 2a we have
.......solve for
go to
..........2a,plug in
your equation is:
determining the vertex: write it in vertex form
=> the vertex is at (,)
and axis of symmetry is
the general form of the equation of the quadratic function:
=> in your case
