Question

Decide whether the function is an exponential growth or exponential decay function and find the constant percentage rate of growth or decay.
f(x) = 2063 ⋅ 0.9953x

Exponential decay function; -0.47%

Exponential decay function; 0.0047%

Exponential growth function; 0.0047%

Exponential growth function; -0.47%

Answer 1

*0.9953^x

Answer 2

decay factor = 0.9953
rate of decay = (1 - 0.9953)*100 = -

Answer 3

it is decay because you have 0.9953
if it is 1.02 it is growth

Answer 4

okay so it is either a or b now how do i figure out which one it is?

Answer 5

why B ?
(1-0.9953)*100=0.47

Answer 6

btw for decay the percentage is always negative
