A graph is not a function if the vertical line intersects the graph at more than point?

Not calculus, but correct.
This is known as the vertical line test and is used to teach the basics of defining a function.

Where is the Y intercept on a graph?
It is the point where the curve (i.e. line) intersects the vertical axis or the y-axis. ... or when x=0.
What is the point at which a graph intersects the y-axis?
A graph intersects the y-axis at the y-intercept; its x value is zero.
How do you graph x is less than or equal to -2?
On your graph, draw a vertical line through the point on the x-axis where [ x = -2 ]." X is less than or equal to -2 " is every point on that line and everything to the left of it.
How do you tell a graph is a function if it touches the y-axis exactly one time?
The main way that a graph can be defined as a function is if it passes the vertical line test; this means that each individual x must correspond to one specific value of y. In the situation you mentioned, we don't know if the graph in question really is a function, because we only see the point at y; we don't know if the graph loops around on itself and fails the vertical line test at any other point.
What test is used to determine if a graph is a function?
Horizontal line test is used for the determination of a function,if the horizontal line passes through one point of the given graph then it is a function and if it passes through more than one point then it will not a function. * * * * * No! It is a vertical line test. Consider the graph of y = sin(x): a horizontal line line will cross it twice in every 360 degrees! Convince me that y = sin(x) 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
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.
If no vertical line intersects the graph of a relation in more than one point then the relation is a function?
True.
What is used to determined if the graph is a function or not?
There is a method called a vertical line test. A function is defined as a system that has one output for each input. Therefore for every x, there is only one y. So if you draw a vertical line anywhere and you get more than one point that intersects the graph, it is not a function. If it intersects only once, the graph is a function.
When does a graph represents a function?
take a vertical line, if another line intersects that vertical line at 2 points, then it is a function.In other words,a graph represents a function if each vertical line meets its graph in a unique point.
What is an example of an x -intercept?
An x-intercept is the point where a function intersects the x-axis on a Cartesian coordinate plane. For example, if the graph of a parabola is plotted and the graph intersects the x-axis on the coordinate plane, the point(s) where the graph intersects the x-axis are the x-intercepts for that function.
Where is the Y intercept on a graph?
It is the point where the curve (i.e. line) intersects the vertical axis or the y-axis. ... or when x=0.
What are the functions in storage tanks?
To test if a storage tank is a function you can use the vertical line test (i.e. if a vertical line can be drawn through the storage tank where it intersects more than one point it is NOT a function). For example: function= vuvu non-function= void (A vertical line intersects two parts of the 'd' and 'o'.)
Why does f represent the graph of a function?
Because each vertical lines meets its graph in a unique point.
What is the point at which a graph intersects the y-axis?
A graph intersects the y-axis at the y-intercept; its x value is zero.
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 is a relation also a function?
A relation is also a function if each member of the domain (or x-coordinate) is paired with only one member of the range (or y-coordinate). If the relation is a set of ordered pairs that consists of real numbers a graph can be created to visualize the relation. If a vertical line can be drawn and only crosses or intersects the graph at one point then the relation is also a function.
