When page be open in blue rectangle type:

x^2+3x-10

Set:

Range x-axis from -6 to 4

Range y-axis from -13 to 7

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.
