Answer:

y=8((1)/(2^x))

Explanation:

Given is a graph which shows decrease in y when x increases.Marked in the I quadrant.

Coordinates in the graph are

(0,8),(1,4)(2,2)(3,1)

We find that for one unit change in x, there is 1/2 change in y

When x increases by 1 units y becomes y/2

So the equation is exponential

Equation satisfying all the coordinates can be written as

y=8((1)/(2^x))
