This graph is not the graph of a function.

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.


Is the graph of a hyperbola a function?

The graph of a hyperbola is not a function because it fails the vertical line test, which states that a graph represents a function if any vertical line intersects it at most once. In the case of a hyperbola, a vertical line can intersect the graph at two points. Therefore, a hyperbola does not meet the criteria to be classified as a function.


What is a way to see if a line on a graph is function?

To determine if a line on a graph represents a function, you can use the vertical line test. If a vertical line intersects the graph at more than one point, then the graph does not represent a function, as it would indicate that a single input (x-value) corresponds to multiple outputs (y-values). Conversely, if every vertical line crosses the graph at most once, the graph represents a function.


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.

Is a vertical asymptote undefined?

Yes, a vertical asymptote represents a value of the independent variable (usually (x)) where a function approaches infinity or negative infinity, and the function is indeed undefined at that point. This is because the function does not have a finite value as it approaches the asymptote. Thus, the vertical asymptote indicates a discontinuity in the function, where it cannot take on a specific value.

Why is it not possible for the graph of a rational function to cross its vertical asymptotes?

A vertical asymptote represents a value of the independent variable where the function approaches infinity or negative infinity, indicating that the function is undefined at that point. Since rational functions are defined as the ratio of two polynomials, if the denominator equals zero (which occurs at the vertical asymptote), the function cannot take on a finite value or cross that line. Therefore, the graph of a rational function cannot intersect its vertical asymptotes.


What is the test that determines if a graph is a function?

The vertical line test determines if a graph represents a function. If a vertical line intersects the graph at more than one point, the graph does not represent a function, as this indicates that a single input (x-value) corresponds to multiple outputs (y-values). Conversely, if every vertical line intersects the graph at most once, it confirms that the graph is a function.


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.
