Answer:
The equation of the parabolic function is :

Step-by-step explanation:
The standard equation of a parabola is given by:

where  represents the vertex of the parabola.
 represents the vertex of the parabola.
From the graph shown in figure we can find the vertex of the parabola which is the minimum point of parabola and lies st point 
So, we can say:
 
Plugging in the values of vertex in standard equation of parabola,

Simplifying the equation:

We can find value of  by plugging in a point from the graph.
 by plugging in a point from the graph.
Using point (0,-2) which lies on graph.
Plugging in the given point.


Adding 3 to both sides.


∴ 
Plugging in  , the equation of parabola can be written as:
, the equation of parabola can be written as:

Answer:
90% confidence interval for the population proportion of US adults who follow baseball 
( 0.1842 , 0.22880)
Step-by-step explanation:
<u>Explanation</u>:-
Given data the survey of 891 US adults who follow baseball in a recent year, 184 said that the Boston red sox would win the world series.
The sample proportion 
                            q = 1-p = 1- 0.20650 =0.79350
<u>Confidence intervals</u>
