Answer:
![100(0.5)^{x}](https://tex.z-dn.net/?f=100%280.5%29%5E%7Bx%7D)
Step-by-step explanation:
According to the graph, the y int is at 100
so that is the starting point
Then at 1 it is at 50
is 2 so that means it is reduced by half
Just to make sure,
is also /2 so that means it is the slope
Since it is a decay, the slope has to be less than one so you get the reciprecol of 2 to get....
