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.
