A relation is a set of ordered pairs.
A function is a relation such that for each element there is one and only one second element.
Example:
{(1, 2), (4, 3), (6, 1), (5, 2)}
This is a function because every ordered pair has a different first element.
Example:
{(1, 2), (5, 6), (7, 2), (1, 3)}
This is a relation but not a function because when the first element is 1, the second element can be either 2 or 3.
Use this cordinate ,find the other cordinate that makes the ordered pair a solution of the given equation: x+4y=7,(_,3)
model
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.
Since you didn't tell us the point given below, we can't answer this accurately.
The vertical line test: Imagine a very large family of vertical lines. If any of the lines intersect with the graph of the relation under consideration at more than a single point then the relation is not a function. (Because a function assigns just one value in the range to a given point in the domain.)
Use this cordinate ,find the other cordinate that makes the ordered pair a solution of the given equation: x+4y=7,(_,3)
Plug your ordered pair into both of your equations to see if you get they work.
You can represent any given function in as many different ways as you want.
x
Given a function, one can "switch" the variables x and y and then solve for y afterwards to determine the inverse function.
model
The function that is given has a constant value and therefore, its slope is 0.
Ordered pairs are represented as functions themselves or they compose a function. They are written as (x, y) as coordinates for their respective function. For example, for the function y=2x, it contains the ordered pairs (0, 0), (1, 2), and so on by plugging in the coordinates for x and y. Where x=0, y=0 because y=2(0). Where x=1, y=2 because y=2(1). To graph ordered pairs, you must be given their respective function(s). From there, it is possible to make a chart of the x and y coordinates in that function, and plot them accordingly.
The functions are periodic and so, given any value (within the range) the function can take the value several times, Graphing the function can help you determine secondary points at which the function takes a given value.
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.
The "sloven's f" is a mathematical symbol used to represent the Fourier transform of a function in signal processing and mathematics. It helps to analyze the frequency components of a given signal or function.
That would depend on the given system of linear equations which have not been given in the question
