Answer:
Step-by-step explanation:
The graph decreases at first, then changes direction at (2, 5). 
y = a(x-2)^2 + 5
Plug in (1,11) and solve for a:
11 = a(1-2)^2 + 5
a = 6
Equation in vertex form:
y = 6(x-2)^2 + 5
 
        
             
        
        
        
100,000 equals 10 to the power of 5, hope helps.
