In MATLAB, you can insert vertical or horizontal lines on a graph by using the xline
or yline
functions, respectively. For example, to add a vertical line at ( x = a ), use xline(a, 'r--')
, and for a horizontal line at ( y = b ), use yline(b, 'g--')
. These lines can help you visually test if a given relation defines a function by checking if any vertical line intersects the graph at more than one point (the vertical line test).
Not quite. You can use a vertical line test on the graph of the inverse mapping, OR you can use a horizontal line test on the original graph. The horizontal line test is used in the same way.
Depends on whether it is vertical or horizontal. If it is vertical, it is undefined. If it is horizontal, it is zero.
depends on whether y=6 or x=6 if y=6 then its a horizontal line if x=6 then its a vertical line
The horizontal line test is used to determine whether a function is one-to-one and if it had a inverse.
A vertical line can be used to test whether or not a graph is a function.
true
This is not always true. High velocity pumps can be found in horizontal configurations too. It all depends on the application (sometimes the manufacturer) whether it will be a horizontal of vertical pump.
A welding position is the orientation of the weld joint, whether that be flat, horizontal, vertical, or overhead.
horizontal line
The answer to this question depends on whether the reflection is in a vertical line or a horizontal line. For example, the reflection of 3 in a horizontal line is 3 but in a vertical line it is E.
A bar graphA graph consisting of bars is called a bar graph. It is irrelevant whether the bars are horizontal or vertical or whether there are spaces between the bars or not.
Determines whether a given mathematical expression is a function or not.
