Answer:
(4,1)
Step-by-step explanation:
The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).
To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.
To find the y-coordinate, input the x=4 and solve for y.

The vertex is (4,1).

Hey there! I'm happy to help!
Quotient means we are dividing. We are dividing A by the difference of 3 and B. Difference means subtract, so our algebraic expression is A/(3-B).
Have a wonderful day! :D
