Question

If f(x) = 3x - 1 and g(x) = x + 2, find (f - g)(x).

Answer 1

(f - g)(x) = 2x - 3

Explanation:

(f - g)(x) is defined as subtracting the whole g(x) function from the f(x) function.

Hence, we can define it as:

(3x - 1) - (x + 2)

= 3x - x - 1 - 2

= 2x - 3

Therefore, (f - g)(x) = 2x - 3.

Hope this helped!
