Given the function:

f(x) = 5x -2

g(x) = 2x + 1

Find (f - g)(x) 

Solution:

Substitute the given values of the function f(x) and g(x) to the equation (f-g)(x).

(f-g)(x) = (5x - 2) - (2x + 1) 

Simplifiy.

(f-g)(x) = (5x - 2) - (2x + 1) 

(f-g)(x) = 5x - 2 - 2x - 1

(f-g)(x) = 3x - 3

Final answer:

(f-g)(x) = 3x - 3
