Answer:
<u>(1, 18)</u>
Step-by-step explanation:
Rewrite the equation in vertex form by completing the square for -3x^2 + 6x + 15. This = -3(x - 1)^2 + 18.
Set y equal to the new right side. 
y = -3(x - 1)
Use the vertex form, y = a(x - h)^2 + k, to determine the values of a, h, and k.
a = -3
h = 1
k = 18
Vertex = (h, k) / (1, 18)
 
        
             
        
        
        
Answer:
I believe it’s the 3rd one.
Explanation:
It’s the only graph where it looks like (2.5,5) was graphed.

Answer:
area of trapezoid/trapezium = 
h=height
a and b are the parallel sides (top 2.5 and bottom 6 in this pic)
so
