Answer:

A. f(x)=56,000(0.93)x+8400

Explanation:

The growth rate is -7%, so the growth factor will be 1 -7% = 0.93. This is the base of the exponential term.

The 8400 special passes will add 8400 visitors to the park in addition to those who pay the regular fee. Thus the number of visitors is ...

f(x) = 56,000(0.93^x) +8400 . . . . matches choice A
