As long as the line represented on the graph has no vertical segments then it may be represented by a function.

That is not enough.
y = sqrt(x) has no vertical segments but it is not a function in the mathematical sense.
A function cannot map an x value to more than one y value. Clearly, the above function maps x to -sqrt(x) and +sqrt(x) and so is not a function. However, there no vertical segment. No matter how close you get to x = 0, there is still a curve and the segment is not vertical.
What else can I help you with?
How do you know if a graph is a function?
A graph is a function if there is no more than one y-value for any x value. This means no vertical lines or "C" shapes, etc
Is a circle graph a function?
No, a circle graph is never a function.
How can you tell if a graph is a sine function or a cosine function?
sine graph will be formed at origine of graph and cosine graph is find on y-axise
Is the first derivative of a function is a constant then its graph is?
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
How can you tell by looking at a graph its a function?
Draw a graph of a given curve in the xoy plane. Now draw a vertical line so that it cuts the graph. If the vertical line cuts the graph in more than one ordinate then given graph is not a function. If it cuts the graph at a single ordinate such a graph is a function.(is called vertical line test)
How do you know if a graph is a function?

What are the rules of continuity of a graph?
If you are looking at a graph and you want to know if a function is continuous, ask yourself this simple question: Can I trace the graph without lifting my pencil? If the answer is yes, then the function is continuous. That is, there should be no "jumps", "holes", or "asymptotes".
What is the relationship between a logarithmic function and its corresponding graph in terms of the log n graph?
The relationship between a logarithmic function and its graph is that the graph of a logarithmic function is the inverse of an exponential function. This means that the logarithmic function "undoes" the exponential function, and the graph of the logarithmic function reflects this inverse relationship.
Is a circle graph a function?
No, a circle graph is never a function.
What is the zero of a function and how does it relate to the functions graph?
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
Draw sketch and write the function of dumper winding and retaining ring?
i need to know how to function rule and a sketch of a graph
How does you know that relation is a function?
One way is to try the vertical line test on a graph!
How can you tell if a graph is a sine function or a cosine function?
sine graph will be formed at origine of graph and cosine graph is find on y-axise
How is the function differentiable in graph?
If the graph of the function is a continuous line then the function is differentiable. Also if the graph suddenly make a deviation at any point then the function is not differentiable at that point . The slope of a tangent at any point of the graph gives the derivative of the function at that point.
Can a line be a graph of a function?
Yes the graph of a function can be a vertical or a horizontal line
Can a line be the graph of a function?
Yes the graph of a function can be a vertical or a horizontal line
How do you know when a graph is not a function?
A function cannot have any value of x mapped to more than one vaue of y. So, if any line parallel to the y-axis meets the graph at more than 1 points it is not a function.
