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)
H=2 if you want me to explain reply to this comment
R=15
explain:
add the numbers in parentheses to get
45/3 = r
divide the numbers to get
15 = r
Answer:
c = $130
Step-by-step explanation:
Given:
c = 100 + 0.30m
Where,
c = cost of renting a car (in dollars)
m = number of miles driven (in miles)
If m = 100 miles
c = 100 + 0.30m
= 100 + 0.30(100)
= 100 + 30
= 130
c = $130
