Can someone work with me to check some of my homework answers?

Suppose that the functions g and h are defined for all real numbers x as follows.

g(x) = x – 2
h(x) = 4x + 2

Write the expressions for (g * h) and (g – h ) (x) and evaluate (g + h) (1).

My answers:
(g * h) (x) = 64
(g – h) (x) = 4x^2 – 6x – 4
(g + h) (s) = 4x^2 + 6x + 4

I believe you are correct. But hold on.

Ok.

blurbendy · Answer

i dont see how you got 64, for g(x) * h(x)

anonymous · Answer

Ok, what did you get?

blurbendy · Answer

(x-2)(4x +2)
then foil

blurbendy · Answer

= 4x^2 -6x -4

blurbendy · Answer

g - x = 
(x -2) - (4x + 2) =
-3x -4

blurbendy · Answer

g - h, not g - x, oops

anonymous · Answer

When I multiplied (g * h) (x) = 64  I got this answer.  

Are you saying all of the answers are incorrect?

anonymous · Answer

Can you tell me what the correct answers are?
