Question

What is the multiplicative rate of change of the exponential function shown on the graph?

A) 2/9
B) 1
C) 4
D) 9/2

Answer 1

...........................................Answer is D

Answer 2

Option: D is correct.

9/2

Explanation:

We have to find the multiplicative rate of change of the exponential function shown on the graph.

We know that a general exponential function is given as:

`y=ab^x`

where b is the multiplicative rate of change.

Now when x=0 we have y=1.

i.e. 1=a

Hence, a=1

and y=b^x

Also,

the graph passes through (1,9/2)

Now when x=1 we have y=9/2

i.e.

9/2=b

Hence, the multiplicative rate of change is:

9/2
