Question

I cant decide if its b or d please help for brainlist !!!!!!!!!!!!!

Answer 1

A is correct! Our base number is 9 since it's at x = 0. The number gets smaller as x increases, so it will be 1/3 instead of 3.

Hope this helps :)

Answer 2

$y = 81( \frac{1}{3} ) {}^{x}$

This is right answer because option d only shows that y are multiples in sequence but this answer shows the correct sequence
