F(x) = 4(3)x and f(5) = 972.

**972 represents the population of the rabbits after five years.**

5 in f(5) represents the year.

4 in f(x) = 4(3)x represents the starting population of the rabbits

3 in f(x) = 4(3)x represents the rate the population increases

x in f(x) = 4(3)x represents the number of years that have passed.

Answer: 3√-20 = 3√20√-1 = (3√20)i

Answer: 16

Well, 9 billion = 9,000,000,000 so in scientific form it would be 9 x 10^9 To get the exponent, just count the number of zeros, which for 9 billion we have 9

**Answer:**

Amira uses 4 balloons to produce each balloon animal

**Step-by-step explanation:**

since Amira uses the same number of balloon for each animal the number is constant **k**

From the table the number of animals sold increased progressively by

**9** each day

From the table the number of balloons remaining decreased by

**36** each day

using this information given to find K

number of decreasing balloons / number of increasing animals sold

k = 36/9 = 4
