Back

Linear

Front

What is the general form of an exponential function?

Back

f(x) = a(b)^x, where a is the y-intercept and b is the base.

Front

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

Back

The factor by which the function grows or decays.

Front

If b > 1 in f(x) = a(b)^x, what type of function is it?

Back

Exponential growth.

Front

If 0 < b < 1 in f(x) = a(b)^x, what type of function is it?

Back
