Which of the following statements is correct? Group of answer choices

The higher the interest rate, the higher the future value of an investment.

All the answers are correct.

The interest earned on interest is the difference between the principal and the simple interest.

The future value is simply the current value of a future cash flow that has been discounted at the appropriate discount rate.

Holding maturity constant, an increase in the discount rate increases the present value of the future cash flow.
