Answer:
21 grapes.
Step-by-step explanation:
We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.
First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.


Now, we will find half of 6 to find number of grapes eaten by Lucy.




Therefore, the three of them eat 21 grapes in all.
If function is 'F' the the inverse would be F^-1 or 'F to the power of negative one.'
The answer is C) 9. The answer is 9 because you have to subtract (5-2) then multiply the answer by 3 which ends up as 9.
