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

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

Step-by-step explanation:

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

This means that you have to subtract the two equation.

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

Then

f (x) - g (x) = [3x - 2] - [2x+1]

= 3x - 2 - 2x - 1

= x - 3

∴ (f - g) (x) = x - 3
