A graph is typically represented in terms of a y-axis (vertical), x-axis (horizontal) and sometimes a z-axis as well (at right angles to the y & x) if it's a 3-D graph.
A vertical line test can be used to determine whether a graph is a function or not. If a vertical line intersects the graph more than once, then the graph is not a function.
Not calculus, but correct. This is known as the vertical line test and is used to teach the basics of defining a function.
Bar graph for amounts. Histogram for amounts over a certain amount of time.
Horizontal line test is used for the determination of a function,if the horizontal line passes through one point of the given graph then it is a function and if it passes through more than one point then it will not a function. * * * * * No! It is a vertical line test. Consider the graph of y = sin(x): a horizontal line line will cross it twice in every 360 degrees! Convince me that y = sin(x) is not a function.
Variables. If you're talking about math.....
A graph is a function if every input (x-value) corresponds to only one output (y-value). One way to check for this is to perform the vertical line test: if a vertical line intersects the graph at more than one point, the graph is not a function.

Algebra
A function can only have one output for any given input. This means that any x value you choose cannot have multiple corresponding y values. The vertical line test involves looking at a graph and drawing vertical lines over it. If any of the vertical lines you have drawn touch the graph of the function more than once, then the graph does not represent a function.
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
This graph fails the vertical line test at x = 3This graph is not the graph of 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.
You could try a speed-time graph, or a distance-time graph.
A mapping diagram can be used to represent a function or a relation true or false?
pie graph
A symbol.
A pie graph would represent the composition of air nicely.
