You are watching: What is the percent rate of change in function y=(0.98)^x
y= 16(0.25)^x
The exponential equation represents an exponential degeneration because the price of decay is 0.25 which is less than 1.
The general form equation is:
y(x)= a(1-r)^x such that r is the decay percent.
Comparing 2 equation we have 1-r = 0.25

y= 16(0.25)^x
The exponential equation represents an exponential decay bereason the price of degeneration is 0.25 which is much less than 1.
The basic develop equation is:
y(x)= a(1-r)^x such that r is the decay percent.
Comparing 2 equation we have actually 1-r = 0.25
Then, the decay percent is 75%.
2. y= 0.8(1.8)^x
The equation represents exponential expansion because the development factor is greater than 1.
Then, the growth percent is 80%
3. y= 17(1/5)^x
The equation represents exponential decay because 1/5 is less than 1.
