what is the equation of the exponential graph shown?

answer:

f(x) = 100/(2ˣ)

step-by-step explanation:

looking at the graph, i got the points

(0, 100)

(1, 50)

(2, 25)

(3, 12.5)

it seems that the functions is exponentially decaying by half for every x-value increase.

so, my function must have the graph start at 100 and decay by 1/2 every time giving me the equation:

f(x) = 100 * (1/2)ˣ

f(x) = 100 * (1ˣ/2ˣ)

f(x) = 100 * (1/2ˣ)       , 1ˣ will always be equal to 1

f(x) = 100/(2ˣ)
