Answer:
A(9) = -52
Step-by-step explanation:
The given sequence is :
A(n)=-4 -6(n-1)
We need to find the 9th term of the above sequence.
To find it, put n = 9 in the above sequence.
A(9) = -4 -6(9-1)
= -4-6(8)
= -4-48
= -52
Hence, the 9th term of the sequence is -52.
Answer:
B. g(x)=(x+7)^2-3
Step-by-step explanation:
Vertex form is F(x)= a(x-h)^2+k
a is the reflection
h and k are the vertex (x,y) = (h,k)
in this case there is no shrink or stretch (a)
if it is translating left or right it is "h". In this case it is translated left so its -7. However if you look at vertex form it is "x-h" so -7-7= +7
If it translating up or down it is "K". In this case it is translated down so its -3.
If it was translated up or right then its positive. If it was translated down or left its negative.
After you figure out what h and k are then you just plug it in. h=-7, k=-3
so the answer in vertex form is, g(x)=(x+7)^2-3
