The graphs below show four functions:

Graph A shows function f of x equals 4 multiplied by 3 to the power of x. Graph B shows function f of x equals 4 multiplied by 3 to the power of negative x. Graph C shows function f of x equals 10 to the power of x. Graph D shows function f of x equals 10 to the power of negative x.

Which graph best shows the function f(x) = 4(3)−x to represent the rate at which a radioactive substance decays?
