Determine the zeros of the following function.
{-1, 5}
{0, 5}
{-5, 1}
{-5, 0}

In this case, a "zero" is an x-value for which the corresponding y-value is 0.

None of the four given points satisfies the function represented by the graph.

Note that (5,0) is a "zero," but is not given as a possible zero.

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 : )
