The table below shows the cubes of different numbers: number (x) 3 −3 5 −5 cube of the number (y) 27 −27 125 −125 part a: does the table represent y as a function of x? justify your answer. (5 points) part b: the total cost f(x), in dollars, for renting a car for x days is shown below: f(x) = 27x + 18 what is the value of f(6) and what does f(6) represent? (5 points)

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
