What is the significance of the original amount 'a' in exponential functions?

• It represents the starting quantity before growth or decay occurs.

• It indicates the rate of growth or decay in the function.

• It is the maximum value the function can reach.

• It determines the time period for the growth or decay.

What is the impact of compounding frequency on exponential growth?

• Less frequent compounding leads to greater growth over the same period.

• More frequent compounding leads to greater growth over the same period.

• Compounding frequency has no impact on growth.

• Growth is only affected by the initial investment amount.

What is the difference between exponential growth and linear growth?

• Exponential growth increases at a constant rate, while linear growth increases at a variable rate.

• Exponential growth increases at a rate proportional to its current value, while linear growth increases by a constant amount.

• Exponential growth is always faster than linear growth regardless of the initial values.

• Linear growth can eventually surpass exponential growth given enough time.
