How do you determine weather the graph represent a function?
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
How to tell if a graph represents a function?
You use the vertical line test. If you can draw a vertical line though the graph and it intersects it only once, it is a function. If the line crosses the graphs more than once it is not.
What is the name of the vertical line?
A vertical line!
What is the slope of a line parallel to a vertical line?
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.
What is a line perpendicular to the vertical?
A horizontal line is a line perpendicular to the vertical.
How can you tell if a graph sHow is a function?
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
How can you tell if a graph that represents the relationship is a function?
The vertical line test! Imagine a vertical line going through all points of the graph. As long as the vertical line only touches the graphed line once, it's a function. If it touches more than once, it is not.
Does a sideways parabola represent a function?
No, it does not. You can tell if something is a function or not by using the vertical line test. If there is more than one point at any vertical line, it is not a function.

How can you tell if a graph show a FUNCTION?
By doing a vertical line test. If you can draw a vertical line and it only passes through the graph once, its a function. If it passes through twice, it is NOT a function.
How can you tell if a function is a function?
The vertical line test can be used to determine if a graph is a function. If two points in a graph are connected with the help of a vertical line, it is not a function. If it cannot be connected, it is a function.

Which way is vertical up or down?
Vertical means up and down. A horizontal line goes from the left to the right (or from the right to the left) like this: ----------------------------- A horizontal line goes from a position that is low to a position that is high (or from a position that is high to a position that is low) like this: | | | | | | | | But the word "vertical" does not tell you which direction the line is drawn, just the it is a line.
How can you tell if a slope is zero or undefined?
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
Why the line x4 is a vertical line?
WHY THE LINE X=4 IS A VERTICAL LINE.
