Question

If f(x) = -3x-5 and g(x)=4x-2, find (f-g)(x)

Answer 1

Answer is (f - g)(x) = -7x - 3

Explanation:

We have:

f(x) = -3x - 5

g(x) = 4x -2

We need to find: (f - g)(x)

So, we can write:

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

= (-3x -5) - (4x - 2)

= -3x - 5 -4x + 2

= - 3x - 4x -5 +2

(f - g)(x) = -7x - 3

So we get (f - g)(x) = -7x - 3

Answer 2

f(x) -g(x) = -3x-5 -(4x-2)

distribute

-3x-5 -4x+2

combine like terms

-7x-3

Answer:

-7x-3
