Question 1206649
Incomplete or unclear.  You HAVE a table of values or you WANT to create one?   If you want to make one, pick a few x values and evaluate the corresponding Y value of each.



{{{-1(x^2-2x-3)}}}


so understand your equation is same as
{{{Y=-1(x+1)(x-3)}}}


and some obvious x values to use are 0, -1, 1, and 3.
