How do you determine whether a graph a mathematical relationship is a function?
Draw a vertical line if the line hits more than one point on the graph then it is not a function.
When do you say that a graph is a function?
In simple terms, if a vertical line meets a graph in more than one place it is not a function.
When can you say that the graph is function or mere relation?
If a vertical line intersects the graph at more than one point then it is not a function.
Why is a graph more informative than an equation?
A graph is more informative than an equation because a graph is easier to interpret visually, and find all the points and line them up, rather than just a slope which shows no points(data).
How does the graph show that the quadratic is a function?
No vertical line will intersect the graph in more than one point. The fundamental flaw is that no graph can show that it does not happen beyond the domain of the graph.
Is a line graph or bar graph more appropriate explain?
A bar graph because its easy and because is very organization than the other line.
Can there be more than one slope on a linear graph?
One line can have only one slope. It is possible to draw more than one line on a single graph, however.
How can you tell whether a graph is a function or not?
A vertical line test can be used to determine whether a graph is a function or not. If a vertical line intersects the graph more than once, then the graph is not a function.
Which statement is a correct interpretation of the vertical line test?
A-If there exists a vertical line that intersects the graph at exactly one point, the graph represents a function.B-If there exists a vertical line that intersects the graph at exactly one point, the graph does not represent a function. C-If there exists a vertical line that intersects the graph at more than one point, the graph represents a function.-DIf there exists a vertical line that intersects the graph at more than one point, the graph does not represent a function
How do you determine whether a graph a mathematical relationship is a function?

Why is it more useful to present results as a line graph rather than a table?
Its more accurate
What can be used to determine if a graph represents a function?
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
When do you say that a graph is a function?
In simple terms, if a vertical line meets a graph in more than one place it is not a function.

No vertical line will intersect the graph in more than one point. The fundamental flaw is that no graph can show that it does not happen beyond the domain of the graph.
How can you tell by looking at a graph its a function?
Draw a graph of a given curve in the xoy plane. Now draw a vertical line so that it cuts the graph. If the vertical line cuts the graph in more than one ordinate then given graph is not a function. If it cuts the graph at a single ordinate such a graph is a function.(is called vertical line test)
