Y= - X/2 = 2 this is the answer
Answer:
I believe that the answer is A
Ok, so we see in
y=a(x-h)^2+k
vertex is (h,k)
vertex is highest or lowest point
on one side, it goes up and other side it goes down
if a is positive, then it goes down then up
if a is negative, it goes up then down
we see
f(x)=2(x+3)^2+2
2 is positive
goes down then up
vertex is (-3,2)
so decreases from -infinity to -3 or ininterval
(-infinity,-3)
answer is first option
Answer:
4x+4
Step-by-step explanation:
Combine like terms:
3x+x= 4x
Add remaining terms (+4)
4x+4
