Answer:
As the given equation represents a quadratic function.
Thus, represents a function.
As we know that the function is just a relation in which each input has only one output.
Thus, represents a relation and function.
Step-by-step explanation:
Given the equation
As the given equation represents a quadratic function.
Thus, represents a function.
As we know that the function is just a relation in which each input has only one output.
Thus, represents a relation and function.
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
The graph is also attached below. From the graph, it is clear that it represents a Parabola.
