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
