Will reward brainliest! 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)

Part A. Notice that , , , and . If we let  represent the number that is being cubed and the result of that operation, we can create the function  whose domain and range are the set of all real numbers.

We can conclude that the table represent the cube function .

Part B. To find the value of , we just need to evaluate the total cost function  at ; in other word, we are going to replace  with 6 in the function:




Since  represent the number of days you are going to rent a car, it  represent the cost of renting a car for 6 days.

We can conclude that the value of  is $180, and it represent the cost of renting a car for 6 days.
