To summarize the previous lesson.
Tick the correct answer-
The purpose of the lesson:
Knowing the vertex is a parabola.
Definition:
A straight line perpendicular to the x-axis and which devides the square function into two identical parts.
Two origins correlated to an identical image and whose position is equally distant from the symmetrical axis.
Conclusion:
The symmetrical axis has to cross the vertex of the graph of the function therefore the function is:
Explanation:
The vertex is characterized by being the only origin of its own image, except for the vertex, the image of each point in the domain has an additional origin.
Important Comment:
The graph of the square function is called: Parabola
