Exponential Decay

Front

True or False: This is an exponential function: f(x) = 3(2)^x.

Back

True

Front

What is the general form of an exponential function?

Back

f(x) = a(b)^x, where a is the initial value and b is the base.

Front

What does the base 'b' indicate in an exponential function?

Back

The growth (b > 1) or decay (0 < b < 1) factor.

Front

How do you determine if an exponential function represents growth or decay?

Back

If the base b > 1, it represents growth; if 0 < b < 1, it represents decay.
