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.

What is the y-intercept?

The y intercept represents?

What does the 2 in the function represent?

The function is:

f (x) = 1,000 · 2^x

x is the number of weeks.

1. y - intercept is : y = 1,000.

2. The y-intercept represents the cicada population at the start (for x = 0).

f (0) = 1,000 · 2^0 = 1,000 · 1 = 1,000.

3. The 2 in the function shows that cicada population doubles every week.
