THere are infinitely many possible functions in any circle graph. Your question needs to be more specific.
There are some relationships but not all relationships are always true. Any function can be represented by an equation. But all equations are not functions. For example, y = sqrt(x) is the equation of the square root relationship which can be graphed as a parabola on its side, but it is not a function. It has slopes at each point. Some functions can be plotted as graphs but not all. A function such as f(x) = 1 when x is rational, and f(x) = 0 when x is irrational has no slope and cannot be plotted as a graph. A graph of a vertical line is not a function.
A linear function is any function that graphs to a straight line. What this means mathematically is that the function has either one or two variables with no exponents or powers. If the function has more variables, the variables must be constants or known variables for the function to remain a linear function.
A title, labeled axes (for graphs), markings on the axes (again, for graphs) and units of measurement. You could use any of the above, based on your context
No, not all chords of a circle pass though the center of that circle. Any cord that does pass through the center of the circle is called diameter of that circle.
No, sorry. WikiAnswers does not use graphs, pictures or diagrams.
Yes, all radii of the same circle are congruent. This means that every radius, which is the distance from the center of the circle to any point on its circumference, is equal in length. As a result, if you measure any radius of a circle, it will always be the same as any other radius of that circle.
Actually, they are useful. At least in some cases.
Graphs that have connected lines or curves are typically referred to as continuous graphs. These graphs represent a function or relationship where the points are connected without any breaks, indicating that for every input within a certain range, there is a corresponding output. Examples include linear functions, polynomial functions, and trigonometric functions. Continuous graphs are important in calculus and mathematical analysis because they allow for the application of concepts such as limits, derivatives, and integrals.
The center of a circle is the same for all circles but the length of the radius can change
There is no specific collective noun for a group of graphs, in which case any noun that suits the context can be used; for example a pile of graphs, a display of graphs, a collection of graphs, etc.
There are infinite diameters in a circle all of the same lengths.
One circle is different from another only in radius or location. All circles are geometrically similar, meaning that you can translate and scale any circle onto any other circle.
