A sliding test. The vertical line can meet the graph at at most one point.
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
base
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.
A derivative of a function represents that equation's slope at any given point on its graph.
No, a circle graph is never 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.
Because f represents a function.
A graph represents a function if and only if every input generates a single output.
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
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!
This graph fails the vertical line test at x = 3This graph is not the graph of a function.
A graph is represents a function if for every value x, there is at most one value of y = f(x).
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.
an exponential function flipped over the line y=x

Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
