Question

The function f(x)= 1000(2)^x where x is the number of weeks, represents the cicada population on a farm. Use a function to answer the following nation.

The y intercept is : A. 0 B. 1000 C. 2000

The y-intercept represents: A. the amount of cicadas initially on the farm.
B. the amount of cicadas on the farm at the end of the week. C. the number of cicadas the population increases by each week. D. the number of cicadas the population decreases by each week.

What does the 2 in the function represent? : A. The number of cicadas doubles every year. B. The number of cicadas doubles every month. C. The number of cicadas doubles every week.

Answer 1

the y intercept is where the line crosses the y axis or where x=0
basically f(0) which is 1000 or B


the y intercept is when x=0, when time=0, so it represents the amount of cicadas initially on the farm


the 2 means it doubles every week (because x=number of weeks)
