Sala's little brother is learning to talk. He has a vocabulary of 30 words. Each week his vocabulary doubles. Find a function rule that models the relationship between the number of weeks and the number of words for Sala's little brother.
+1622 Today we can set as day 'n'.
Each week, his vocab doubles, so on the next week the day would be 'n + 7', and his vocab would be 2(30).
For 'x' weeks, the day would be n + 7x. The vocabulary corresponding to that would be 30 * 2x.
You can do the job of writing the function rule.
:D hope it helps
