What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a ⋅ b^x, where 'a' is a constant and 'b' is a positive real number.

Front

What is the general form of an exponential growth function?

Back

f(x) = a ⋅ b^x, where b > 1.

Front

What is the general form of an exponential decay function?

Back

f(x) = a ⋅ b^x, where 0 < b < 1.

Front

How do you identify exponential growth from a function?

Back

If the base 'b' is greater than 1, the function represents exponential growth.
