The axis of symmetry is the fold line that splits the parabola down the middle.
Now, since a parabola is symmetrical, every point, except the vertex, will have a mirror image of another point if we folded the parabola over the axis of symmetry.
So if we know the axis of symmetry is x = 3 and one of our points
has the coordinates (5, 0), the other point will have the coordinates (3, 0).
The axis of symmetry is always halfway between the x-intercepts.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
 has the form
 has the form  known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.
 known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.


The factored for is (a+b)(a-b).
In this case, it is 
 
        
                    
             
        
        
        
Answer:
The Chi-square test of independence
Step-by-step explanation:
The answer to this question is the Chi-square test of independence because it is what is used to determine the existence of an association between nominal/categorical variables. This test is non parametric in nature and it can also be called the chi square test of association.
The data is tabulated. each row is a representation of the category for one of the variables and each column is for the other variable.
