The set of ordered pairs represents a function {(4,3), (-5, -5), (4, 6), (-2,8)}
represents the function.
Because every x-value corresponds to exactly one y-value.
A function states that it is a relation in which every domain value is paired with exactly one element of range.
Given the set of ordered pair:
{(4,3), (-5, -5), (4, 6), (-2,8)}
Domain is all the x-values, and range is all the y-values.
Domain: {4, -5, 4, -2}
Range: {3, -5, 6, 8}
By definition:
each input value (i.e. x values) is paired with exactly one element of y-value.
Therefore, the set of ordered pairs {(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)} represents the function.
An expression, rule, or law in mathematics that establishes the connection between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
