Noe find the mean of 25 and 17 and 17 and 9
mean = 
= 
= 21 and
mean = 
= 
= 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
5 is a prime factor of 155. Dividing 155 by 5, we get 31. 1*5*31 = 155.
To find f(g(x)), plug g(x) into f(x) and simplify.
f(x/2) = 2 - 1/(x/2)
All you have to do is simplify the right side of the equation.
Take it from here.
