Front

In an exponential function, what does the 'a' represent?

Back

y-intercept

Front

What is the range of an exponential function?

Back

(0, ∞) (all positive real numbers)

Front

What is the general form of an exponential function?

Back

f(x) = a(b)^x where a > 0 and b > 1 for growth, 0 < b < 1 for decay.

Front

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

Back

The rate of growth or decay.

Front

How do you identify exponential growth from a table of values?

Back

The values increase by a constant factor.

Front

How do you identify exponential decay from a table of values?

Back
