Answer: A, E and F.
Step-by-step explanation:
A simple exponential function is something of the form
f(x) = a*r^x
a is the initial amount
r is the factor of increase of decrease.
x is the variable.
then any increase or decrease by a given factor can be related to a exponential function so options A and E can be related to exponential functions.
Particularly, the option F says that the increase is by 23%.
So we have that the increase is:
A to A + 0.23*A = 1.23*A
So we have a factor of 1.23, this is also an exponential function.
