How do you use a vertical line test to determine if a graph represents a function?
A vertical test line is useful because, by definition, a function has one and only one result value for each input value. If you can find a vertical line that intersects the curve of the line, then it is not a function. A simple example is a circle.
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 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.
What do you call a function whose graph is a non-vertical line?
It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.
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.
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 represents the point on the vertical axis and also describes the initial amount of a function?
It is the y-intercept.
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.

How does the vertical line test determine if a graph represents a function?
Functions cannot have two y-values (outputs) for any single x-value (input), so if you can draw a vertical line that touches more than 1 point on the graph, it is not a function.
What part of speech is vertical?
Vertical is an adjective.
What kind of verticle-line test determines which graph represents a function?
A sliding test. The vertical line can meet the graph at at most one point.

It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.

What are the functions of a line?
f(x) = mx + bRestate the question: What are the functions that can represent a straight line?The equation y=mx + b represents all straight lines except for a vertical line, which has undefined slope.In function form, this is f(x) = mx + b. m represents the slope, and b the y-intercept.x = a represents a vertical line, which is not a function.The 'general form' of the straight line equation is Ax +By + C = 0. As long as B is not zero, this is a function.
