The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.

What do the asymptotes represent when you graph the tangent function?

When you graph a tangent function, the asymptotes represent x values 90 and 270.


What do you use to determine whether a graph shows a function?

To determine whether a graph represents a function, you can use the vertical line test. If any vertical line drawn on the graph intersects the curve at more than one point, the graph does not represent a function. This is because a function must assign exactly one output value for each input value. If every vertical line intersects the graph at most once, then it is a function.


How can one determine the median from a graph?

The answer depends on what the graph is of: the distribution function or the cumulative distribution 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 can you tell from the graph whether or not it is a function?

To determine if a graph represents a function, you can use the vertical line test. If any vertical line drawn on the graph intersects it at more than one point, then the graph does not represent a function. In contrast, if every vertical line intersects the graph at most once, then it is a function. This test helps ensure that each input (x-value) corresponds to exactly one output (y-value).

What do the zeros of a polynomial function represent on a graph?

The zeros of a polynomial represent the points at which the graph crosses (or touches) the x-axis.


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.


Why does f represent the graph of a function?

Because each vertical lines meets its graph in a unique point.


How do you determine if a relation represents a function?

If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!


Does a circle represent a function in linear functions?

a) A circle is not the graph of a function. b) A circle is not linear.


How can you determine if a relationship between two variables is a function from a graph?

The relationship is a function if a vertical line intersects the graph at most once.


How can you tell if a function is a function?

The vertical line test can be used to determine if a graph is a function. If two points in a graph are connected with the help of a vertical line, it is not a function. If it cannot be connected, it is a function.


How do you determine whether a graph of a mathematical relationship is a function?

If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
