Answer: 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
- We call 'b' growth factor when b>1, we can write b= 1+r , where r is the rate of growth.
- We call 'b' decay factor when b<1 , we can write b= 1-r , where r is the rate of decay.
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%.

Answer:
My age is 78 years.
Explanation:
Define my age first as a variable.
Let my age be
