The graph of a quadratic function is a parabola whose axis of symmetry is parallel to the y-axis.
The formula for the line of symmetry:
h = – b / 2 a
In this case :
a = 1
b = 3
h = –b / 2 a
h = - 3 / 2 * 1 =
h = - 3 / 2
x , y table:
x = - 3 , y = - 10
x = - 2 , y = - 12
x = - 1 , y = - 12
x = 0 , y = - 10
x = 1 , y = -6
x = 2 , y = 0
x = 3 , y = 8
etc.
X=x^2+3x-10. Graphed as a parabola
Include the x,y table please.
And line of symmetry.
