Question 372260: Suppose that the functions g and h are defined for all real numbers x as follows.
g(x)=x-4
h(x)=4x+2
Write the expression for (g-h)(x) and (g*h)(x) and evaluate (g+h)(-2)
(g-h)(x)=
(g*h)(x)=
(g+h)(x)=

(x)\ =\ g(x)\ -\ h(x)\ =\ (x\ -\ 4)\ -\ (4x\ +\ 2))
(x)\ =\ g(x)\ \cdot\ h(x)\ =\ (x\ -\ 4)(4x\ +\ 2))
(x)\ =\ g(x)\ +\ h(x)\ =\ (x\ -\ 4)\ +\ (4x\ +\ 2))
You get to simplify these yourself.
Once you simplify the last one, substitute -2 for 
and do the arithmetic.
