Answer:

(f-g)(x) = 4x - x^(-5)

Step-by-step explanation:

Please, enclose that negative exponent inside parentheses:  g(x)=x^(-5).  No need to type in the " + " in f(x)=4x^+1.

g(x) is to be subtracted from f(x).  Write f(x):

f(x)=4x

followed by the negative of g(x):  -g(x) = -x^(-5)

and now combine these two results:

 f(x)=4x

-g(x)= -x^(-5)

---------------------

(f-g)(x) = 4x - x^(-5)
