Front

Define an exponential function.

Back

A 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 an exponential function from a set of points?

Back

If the ratio of consecutive y-values is constant, the function is exponential.

Front

What is the y-intercept of the function f(x) = 5^x?

Back

(0, 5) because f(0) = 5^0 = 1.
