Back

The growth or decay factor.

Front

If a function is in the form f(x)=a(b)^x, what does 'b' represent?

Back

The common ratio.

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

How do you determine if an exponential function is growing or decaying?

Back

If b > 1, it is growing; if 0 < b < 1, it is decaying.
