Answer:
y = 12
Step-by-step explanation:
The standard form of the exponential function is
y = a
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a (
= 1 ), so
a = 12, then
y = 12
Using (1, 34.8 ) , then
34.8 = 12 ( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12
You can work out the percentage change and that would help you work out the rate of appreciation :)
The formula is ((new value - old value)/old value) * 100.
So you do
Therefore the rate of appreciation is 8% p/a.
