Answer:
y = 2(x + 2)^2 – 5
Step-by-step explanation:
When y = ax^2 +bx +c is written in vertex form, it becomes ...
y = a(x +b/(2a))^2 +(c -b^2/(4a))
The constant term in the squared binomial is b/(2a) = 8/(2(2)) = +2. Only one answer choice matches:
y = 2(x +2)^2 -5
The answer for the question above is the B/Second one or
Y=3(1/3)^x
