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.

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
