Were you given an expression for $g(x)?$ If so I expect it was $g(x) = x(x2).$ To obtain an expression for $g(x+1)$ you need to look at the expression for $g(x)$ and every time you see $x$ replace it by $(x+1).$ thus \[g(x + 1) = (x + 1)(x + 1  2) = (x + 1)(x  1).\] Does this answer you concern about $g(x+1)?$ Which graph do you find strange, the graph of $y = g(x)$ or the graph of $y = g(x+1)?$ Penny
