Answer:
A'
Step-by-step explanation:
i think it is, sorry if im wrong
 
        
                    
             
        
        
        
First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry 
1st: group the number 
(X2+6x)-9
2nd: use b/2 
6/2 = 3 , 3^2= 9
(X2+6x+9)-9-9
(X2 + 3)-18
Vertex is 3,-18 so the symmetry is 3
        
             
        
        
        
Using the z-distribution, it is found that the 95% confidence interval is (0.46, 0.526), and it does not provide strong evidence against that belief.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
 is the sample proportion. is the sample proportion.
In this problem, we have a 95% confidence level, hence , z is the value of Z that has a p-value of
, z is the value of Z that has a p-value of  , so the critical value is z = 1.96.
, so the critical value is z = 1.96.
We have that a random sample of 864 births in a state included 426 boys, hence the parameters are given by:

Then, the bounds of the interval are given by:


The 95% confidence interval estimate of the proportion of boys in all births is (0.46, 0.526). Since the interval contains 0.506, it does not provide strong evidence against that belief.

value of x is: 
Step-by-step explanation:
We need to solve the equation f(x)=g(x)
where 
and 
Solving to find f(x)=g(x)
Putting values of f(x) and g(x)

So, value of x is: 
The graph will be a straight line x= -2.58 or x = -31/12
