Given the function:

f(x) = fx^3 -2

g(x) = x + 1

Find (f - g) (x)

Solution:

In order to find the given condition, we equate the functions in one solution separated by a minus sign.

(f - g) (x)= (x^3 - 2) - (x  + 1)

(f - g) (x)= x^3 - 2 - x  - 1

(f - g) (x)= x^3 - x  - 3

Final answer:

(f - g) (x)= x^3 - x  - 3
