Question 2

The total amount of money, f(x), in a savings account after x years can be represented by. f(x) = 3000(1.065)'. What is the range of the function?

Answer 1

The formula to find the amount is

The given function is

Comparing them we get

Subtracting 1 from both sides

Multiplying by 100 on both sides

Answer 2

Answer: 0 < x <= 3000

Explanation:

0 < x <= 3000

(the cost can't be negative so it has to be greater than 0, it cannot be equal to 0 since 0 is an asymptote of the graph)

(the cost is less than 3000 because the graph decreases from the (0, 3000) so the graph cannot be above that point)
