How you will know that the graph and the given equation into variables represent a function?

The graph or function relates a value y (in the vertcal direction) to a value x (in the horizontal direction).
For each point x in the domain, there must be one and only one value y. In terms of a graph that means that a vertical line from any value of x in the domain must meet the graph in exactly place - at least once and not more than once. More than one x values can have the same y value associated with them.

What can a triangle represent in a periodic equation?
In a periodic equation a triangle can be used to represent the given change of something.
Does the equation 2y5x 1 represent a direct variation?
Without an equality sign the information given does not represent an equation.
What does solve an equation of two variables given a domain?
2+2
Is The equation 4x 6y24 is an equation in two variables?
Without an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be an equation.
When do you say that the equation is a function or not?
i may only be 10 yrs old but i can say that an equation is not an function like the graphs of quadratic functions you will only be given an equation
Is the linear equation X equals -14 a function?
No, this is not a function. The graph would have a vertical line at x=-14. Since there are more than one y value for every given x value, the equation does not represent a function. The slope of the equation also does not exist.

How can you tell if it not function of x?
If what is meant is that the exercise asks whether or not y is a function of x, then it can be determined by a brief experiment with the numbers and variables presented in the equation written. If y is isolated from x depending on the organization of whichever total side of the equation where both variables are written, then it becomes simpler to find whether or not y is a function of x. For example, if the equation is written y2 = x + 4, then y is a function of x because x and y are isolated to different sides of the equation. But if the equation is written, for instance, as y2 + 5x = 4, then y is not a function of x because x and y are not isolated to different sides of the given equation. Furthermore, this rule does not depend upon fractions or estimations. The rule holds true because y is a function of x if x and y are related according to the format of the whole equation and the numbers it contains.
When you are given a graph how can you come up with a rational function equation?
You cannot, necessarily. Given a graph of the tan function, you could not.

Why are function notation important?
A function is a relationship between quantities (variables) that occurs when the value of one of the quantities can be given uniquely by specified values of the other quantities. The variables involved can be either independent or dependent. The values of certain variables are fixed while others are allowed to change. The fixed variables are called the independent variables, and the dependent variables are those that change in response to the given value of the independent variable. A function therefore relates dependent variables to independent variables, the only restriction being that each value of the dependent variable is given uniquely by one, and only one, value for each of the independent variables.
What is a table of ordered pairs that represent solutions of a function?
Use this cordinate ,find the other cordinate that makes the ordered pair a solution of the given equation: x+4y=7,(_,3)
How do you illustrate an inverse function?
Given a function, one can "switch" the variables x and y and then solve for y afterwards to determine the inverse function.
