An important property of the exponential function is that:
A) if x changes by 1 unit, then y changes by a constant percentage that is approximately equal to the model constant b times 100%
B) if x changes by 1 unit, then y changes by a constant percentage that is approximately equal to the model constant b%
C) if x changes by 1%, then y changes by a constant percentage that is approximately equal to the model constant b times 100%
D) if x changes by 1%, then y changes by a constant percentage that is approximately equal to the model constant b%
