##### the number f of antelope in a population can be molded by the function

 Algebra Tutor: None Selected Time limit: 1 Day

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:

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

step 3 didn't fit actually haha  could you finish? step 3: find the percentage by which the function decreases per unit of x. divide successive values of the function and subtract from 100 percent. f(1)/f(0)=272/320=0.85        1-0.85=0.15.05 15%  the population has decreased by 15% each year since 2003

step 3:  320 - 272 / 320 = 48 /320 = 0.15 x 100 = 15%

The population decreases by 15% each year
