Question

Hey there! posted picture of question help please

Answer 1

For this case we have the following function:
 f (x) = (1/6) ^ x
 We must evaluate the function for x = 3
 We have then:
 f (3) = (1/6) ^ 3
 Rewriting:
 f (3) = (1/216)
 Answer:
 The function evaluated at x = 3 is:
 f (3) = (1/216)
 option C

Answer 2

The answer is C..

F(3) = (1/6)³
F(3) = 1/216

All you had to do is cube the 6 since the cube of 1 is the same.

Hope this helps :)
