Question

the growth of a species of fish in a lake can be modeled by the function f(x)=500(1.10)^x, where x is time in months since january 2019. what does the 500 represent? the number of fish after the first month. the starting number of fish in the lake. the monthly growth rate of the fish. the number of fish at the end of the first year.

Explanation:

In an exponential - growth function of the form $y = a(1 + r)^x$, $a$ represents the initial amount. Here, the function is $f(x)=500(1.10)^x$, so 500 is the starting number of fish in the lake.

Answer:

The starting number of fish in the lake.
