Percentage of down payment that ABC bank requires to be paid = 20%
Price of the house = $10500
Then
Amount of down payment 
that needs to be made = (20/100) * 105000
                                     = 21000 dollars
From the above deduction, it can be deduced that the correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has actually come to your desired help.
        
                    
             
        
        
        
We have been given graph of a downward opening parabola with vertex at point  . We are asked to write equation of the parabola in standard form.
. We are asked to write equation of the parabola in standard form.
We know that equation of parabola in standard form is  .
.
We will write our equation in vertex form and then convert it into standard form.
Vertex for of parabola is  , where point (h,k) represents vertex of parabola and a represents leading coefficient.
, where point (h,k) represents vertex of parabola and a represents leading coefficient.
Since our parabola is downward opening so leading coefficient will be negative.
Upon substituting coordinates of vertex and point (0,0) in vertex form, we will get:




 Divide both sides by
 Divide both sides by 
So our equation in vertex form would be  .
.
Let us convert it in standard from.



Therefore, the equation of function is standard form would be  .
.
