If the odd function is continuous, it must pass through (0,0) as the property of odd function is that the graph of the function is rotational symmetrical about the origin.

Substitute (2,-2) into g(x) = f(x+3) - 5.

\(-2 = f(5) - 5\\ f(5) = 3\)

From this, we get \(f(-5) = -3\).

When x = -8,

\(g(-8) = f(-5) - 5\\ g(-8) = -3-5 = -8\).

So it must also pass through (-8,-8).

 

Answer: (0,0), (-8,-8)

Max continuity is not needed

 

EDIT: I don't think g(x) must pass through (0,0), f must pass through that point

 

g(x) will pass through (-3,-5)

This kid of looks like its a problem for AOPS. (I'm just going to assume it is) You can always ask on message boards, or read the textbook if it is.
