If we have a table of values as our only information about a quadratic function, we can still determine many key features. As always, the y intercept is the point where the xvalue is zero. The xintercepts (there could be zero, one, or two) are the point(s) where the yvalue is zero. If you imagine a parabola graph, you know that the vertex represents either the highest yvalue or the lowest yvalue, depending on whether the parabola opens up or down. Look for a change in the y values from increasing to decreasing (or visaversa) to locate the vertex.
