Answer:

(f−g)(x) = −x + 6.

Explanation:

Given:

  • f(x) = x+5
  • g(x) = 2x−1

To find:

  • (f−g)(x)

Solution:

To find- (f−g)(x), we need to subtract g(x) from f(x).


\sf \sf (f-g)(x) = f(x) -g(x) = (x+5) - (2x-1)


\sf = x+5 - 2x + 1


\sf = (1-2)x + (5+1)


\sf = -x + 6

Therefore, (f−g)(x) = −x + 6.
