Answer:
any of them work
Step-by-step explanation:
For every
, we have

So, negletting the first term, each term of the sum is greater than 1, which implies

Which means that the series diverges.
Answer:
-3(3+4x)
Step-by-step explanation:
C, nether of the problems have any repeating coords.
F(x)=a(x-h)^2+k
vertex is (h,k)
f(x)=1(x-6)^2-31
f(x)=1(x-(6))^2+(-31)
h=6
k=-31
vertex=(6,-31)
