Question

If the expression 400(1.12)y gives the number of fish in a man-made lake y years after fish were placed in the lake, which statement is true?

Answer 1

The expression 400(1.12)^y is an exponential function

The true statement is that the growth rate of the fish in the lake is 12%

How to determine the true statement?

The expression is given as:

400(1.12)^y

The above expression is an exponential growth function,

Where:

• 4000 represents the initial value
• 1.12 represents the growth factor

Next, we calculate the growth rate (r) as follows:

r = 1.12 - 1

r = 0,12

Express as percentage

r = 12%

Hence, the true statement is that the growth rate of the fish in the lake is 12%
