Description
f(t)=320(0.85),where t is the time, in years, since 2003 answer these questions: A:what is the significance of the function value f(0)? what is the value. B: does the function model exponential growth or decay? C: what percentage does the function increase or decrease per unit of t? 1)find and interpret f(0).320(0.85)=320 at time =0.in the year 2003 there were 320 antelope. step 2:determine if the function models growth or decay. find f(1) and compare it to f(0) 320(o.85)=320(0.85)=272 step3:
Explanation & Answer
I'm assuming you meant f(t) = 320(0.85)^t
Then,
A. f(0) represents the initial population of antelope in 2003. The value is 320.
B, The function models exponential DECAY since 0.85 < 1.
C, The function is decreasing by 15% per unit of t
1) f(0) = 320(0.85)^0 = 320(1) = 320. This was the dear population in 2003.
step 2: The function models decy.
f(1) = 320(0.85)^1 = 272
320 - 272 = 48 which means there was a decrease in the population of dear by 48 in one year.
step 3: no step was given here
