Answer:
B) 25
Step-by-step explanation:
Given exponential function:

The growth factor between
and
is 25.
To find the growth factor between
and 
Solution:
The growth factor of an exponential function in the interval
and
is given by :

We can check this by plugging in the given points.
The growth factor between
and
would be calculated as:



Plugging in values.

(On canceling the common terms)
(Using quotient property of exponents
)

∴
Similarly the growth factor between
and
would be:



Plugging in values.

(On canceling the common terms)
(Using quotient property of exponents
)

∴
Thus, the growth factor remains the same which is =25.
