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.
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.
What is the word perpendicular mean?
Intersects at a right angle, also vertical.
What is the point in the coordinate plane where the horizontal axis intersects the vertical axis?
This point is the origin.
When do you say that graph is function?
A graph is a function if any vertical line intersects it at most once.
If no vertical line intersects the graph of a relation in more than one point then the relation is a function?
True.
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.
A function will always be a vertical line?
A function can never be a vertical line, because it then fails the definition of a function: every x value outputs only 1 y value. The vertical line test will determine if a relation is a function. If a vertical line intersects the graph of the function at more than one place, it 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

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'.)
What is an angle formed when a vertical line intersects a horizontal line?
Right angles (90 degrees) will be formed.
The vertical change in a relation to slope?
Rise
Is a vertical line a relation?
Yes it is, but it is not a function.
