The table represents an exponential function. What is the multiplicative rate of change of the function?
(A)1/3 (B)2/3 (C)2 (D)9
Answer:
(B)
Step-by-step explanation:
An exponential function is a function of the form
where a is the initial value and b is the multiplicative rate of change
When x=2, y=6, we have:
When x=3, y=4, we have:
Dividing the two equations:
The multiplicative rate of change, b is .
The correct option is B.
Answer:
Table B
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

The values of k are the same
therefore
The table B shows y as DIRECTLY PROPORTIONAL to x
