Answer:
40
Step-by-step explanation:
Answer is 2
Step by step exploration
2+1.25f=10-2.75f
1.25f+ 2.75f=10-2
4f=8
f=2
II. f(x) doubles for each increase of 1 in the x values. Thus, r must be 2, and so we our ar^1 = 6 from ( I ) above becomes f(x) = a*2^x. Applying the restriction ar^1 = 6 results in f(1) = a*2^1 = 6, or a = 3.
Then f(x) = ar^x becomes f(x) = 3*2^2 (Answer A)
The answer is C or D but I think its most definitely C
