If my math is correct. I am sorry if I am wrong
So lets try to prove it,
So let's consider the function f(x) = x^2.
Since f(x) is a polynomial, then it is continuous on the interval (- infinity, + infinity).
Using the Intermediate Value Theorem,
it would be enough to show that at some point a f(x) is less than 2 and at some point b f(x) is greater than 2. For example, let a = 0 and b = 3.
Therefore, f(0) = 0, which is less than 2, and f(3) = 9, which is greater than 2. Applying IVT to f(x) = x^2 on the interval [0,3}.

Answer:

Step-by-step explanation:
Let
y-----> the trout population
x----> the time in years
we know that


----->exponential function that models the trout population
$3.25 is the other 1/4. So $3.25 x 4 is $13 (their total). They spent $9.75
