Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y = 940(1.89)

 The change represents  growth with 89% of growth rate.

Step-by-step explanation:

The exponential function is given by :-

... (i)

Where , A = initial value , b= multiplicative factor and  x= time period

The given function : .

By comparing this to (i) , we get

b= 1.89 > 1 , thus it represent the growth.

Also,

i.e. Percentage rate of growth = 0.89 x 100 = 89%.

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
