Question

What does the "b" value represent in the general form of an exponential function?
y = a(b)^x



A.
common ratio or growth/decay rate

B.
initial value or common ratio

C.
common ratio or x-intercept

D.
initial value or y-intercept

Answer 1

The "b" value in the general form of an exponential function \( y = a(b)^x \) represents the common ratio or growth/decay rate. Specifically:

- If \( b > 1 \), it indicates exponential growth.
- If \( 0 < b < 1 \), it indicates exponential decay.

Thus, the correct answer is:

**A. common ratio or growth/decay rate**.
