State any restrictions on the variables 9x-3x^2/x+3

Since you cannot divide by 0, you have to make sure the denominator never equals zero.
-3 is the only number for x that will make J the denominator zero, so therefore X cannot be -3

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
