Answer:the awnser is C

Step-by-step explanation:I realise you’ve probably gotten past this question, but I’m throwing it out for all future askers of this question Â¯\_(ãƒ„)_/Â¯

C) Æ’(x) increases by a factor of 3

Æ’(x) increases by a factor of 3

f(4) = 3^4

f(5) = 3^5

f(5)

/f(4) Â = Â 3^5

/3^4 Â = 3^5âˆ’4 = 3^1 = 3

The value of Æ’(x) changes from 81 to 243 over the interval from x = 4 to x = 5.

This is an increase by a factor of 3.
