(f-g)(x) and (g-f)(x) are the same function. This statement is:

- true for most functions f(x) and g(x)

- always true

- always false

- false for most function f(x) and g(x)

(fg)(x) and (gf)(x) are the same function. This statement is:

- true for most functions f(x) and g(x)

- always true

- always false

- false for most function f(x) and g(x)

For two functions q(x) and p(x),

p(x)+q(x) = q(x)+p(x), is:

- this statement always true

- this statement sometimes true if the two functions are of the same dergee

- the statement sometimes true of q(x) and p(x) are not rational functions

- this statement never true

the sum of two functions p(x) + q(x) will have the same intersection point as the intersection of p(x) and q(x), is;

- this statement always true

- this statement sometimes true

- this statement never true
