Choose among these options the one that results in a graph that shows exponential decay. a. f(x) = 0.6(2)x b. f(x) = 3(0.7)x c. f(x) = 0.4(1.6)x d. f(x) = 20(3)x

B. f(x) = 3(0.7)ˣ
Decay means an overall decrease in the original value. Exponential equations are written in the form:
amount after time n = original amount x (decay OR increase factor)ⁿ
The value of the factor is less than one in the case of a decay.

The answer is lol i dont know
