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

Back

Y-INTERCEPT

Front

Write the explicit formula for the geometric sequence: a_n = ?

Back

Front

Is this exponential growth or decay?

Back

Growth

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

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

Back

The growth (b > 1) or decay (0 < b < 1) factor.

Front

How do you find the y-intercept of an exponential function?

Back

Set x = 0 in the function f(x) = a * b^x.

Front

What is the common ratio in a geometric sequence?

Back

The factor by which each term is multiplied to get the next term.

Front

If a function is increasing, what type of function is it?

Back

Exponential growth.
