Question

Marcus buys $1,000 worth of stock in a company. He expects the value of the stock to increase by 5% each year.



Which equation could Marcus use to predict the stock's value x years after he purchases the stock?

A.
f(x) = 1,000(5)x

B.
f(x) = 1,000(x)5

C.
f(x) = 1,000(1.05)x

D.
f(x) = 1,000(x)1.05

To predict the stock's value after \( x \) years with an annual increase of 5%, Marcus would use a formula that reflects exponential growth based on the initial investment and the growth rate.

The correct equation that represents this situation is:

**C.** \( f(x) = 1,000(1.05)^x \)

This equation shows that the initial investment of $1,000 will grow by a factor of \( (1.05) \) for each year \( x \).
