How do you find the axis of symmetry, vertex and x intercepts for #y=x^2+x-6#?
2 Answers
the vertex will be
the axis of symmetry is simply
Explanation:
The first thing to do is to complete the square
add half the coefficient of
the terms in red give a perfect square
the vertex will be
basically this is the translation of
graph{x^2+x-6 [-10, 10, -5, 5]}
the axis of symmetry is simply
the
Axis of symmetry:
Vertex is at
Explanation:
The quadratic is in the form
The axis of symmetry is found from:
The vertex lies on the axis of symmetry.
You have the
Vertex is at
To find the
(The average of the x-intercepts confirms the axis of symmetry)
