F (x) = x + 8 and g (x) = - 4x - 3, find (f-g) (x)

5x + 11

Step-by-step explanation:

We are subtracting function g (x) from function f (x).

Write f (x) as is: f (x) = x + 8.

Then change all of the signs of g (x) : - g (x) = 4x + 3.

Now combine like terms for the sum (f - g) (x) = x + 8 + 4x + 3. We get

(f - g) (x) = 5x + 11
