Exponential Review

If an exponential function is growing, what is the relationship between b and the rate of growth?

• As b gets smaller, the rate of growth increases.

• As b gets larger, the rate of growth increases.

• As b gets larger, the rate of growth decreases

• As b gets larger, the rate doubles.
