If you look at it on a graph, the domain is any value on the x-axis (horizontal line), while the range is any value on the y-axis (vertical line).
Because, if the Domain(x-values) repeats, when graphed on a coordinate plane, there will be multiple dots in a vertical line. If you were to conduct the Vertical Line Test, and there are two points in one straight vertical line, this would not be a function. If the Range(y-values) repeats, this would be a function, because if the Domain is different, then there will be no points plotted in the same line.
A vertical line goes straight up an down, so a vertical line segment is a line segment that goes straight up and down. Simple.
Yes a undefined slope is a vertical line so the domain would be a single number and the range would be all reals
A vertical line!
A vertical test line is useful because, by definition, a function has one and only one result value for each input value. If you can find a vertical line that intersects the curve of the line, then it is not a function. A simple example is a circle.
WHY THE LINE X=4 IS A VERTICAL LINE.
A horizontal line is perpendicular to a vertical line.
It is a line that is vertical from a line segment or a intersecting line .
A horizontal line is a line perpendicular to the vertical.
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
all vertical lines are parallel to waht type of line?
