WORLD'S HARDEST MATH QUESTIONS

Scientists released 6 rabbits into a new habitat in year 0. Each year, there were four times as many rabbits as the year before. How many rabbits were there after x years? Write a function to represent this scenario.

Answer 1

Answer A Is correct Because it is the right answer I got it right on my quiz

Answer 2

ok, so in year 0, the number of rabbits is 6 which is 6*(4)^0

in year 1, the number of rabbits is 4*6 which is 6*(4)^1

in year 2, the number of rabbits is (4*6) from year one multiplyed by 4, so a total of rabbits is 4*6*4 which is 6*(4)^2

in year 3, the number of rabbits is 6*(4)^2 from year two multiplyed by 4, so a total of rabbits is 4*6*4*4 which is 6*(4)^3

The sequence will continue in the same way.
Therefore, for year x:
f(x) = 6 * (4)^x which is choice A
