Answer:
6.7-(-2.5)=9.2 6.7+(-2.5)=4.2 Neither
2.5 + 6.7 6.7 - 2.5 2.5 - 6.7
-2.5 + 6.7 -2.5 - 6.7
-6.7 + 2.5
Answer:
The second graph is the correct graph
Step-by-step explanation:
Answer: I think is B or A
Step-by-step explanation:
Answer:
f(1) = 2
f(n) = 2 × f(n - 1) , n ≥ 2
Step-by-step explanation:
the point of coordinates (1 , 2) is on the graph
Then
f(1) = 2
…………………………
We notice that :
f(2) = 4
f(3) = 8
f(4) = 16
16/8 = 8/4 = 4/2 = 2/1 = 2
________________________
This means the common ratio
of the geo sequence = 2
Hence ,
f(n) = 2 × f(n - 1)
