Final answer:
The amount initially invested in the function у = 3500 • 0.975х is $3,500, calculated by evaluating the function when x = 0.
Step-by-step explanation:
The question asks about the amount initially invested in an investment function which is modeled by
у = 3500 • 0.975х. To find the initial investment, we need to evaluate the function at x = 0, because that represents the starting point of the investment before any changes due to interest or depreciation occur.
When x = 0, the equation simplifies to y = 3500, because any number raised to the zero power is 1.
Therefore, the amount initially invested is $3,500.
