Select the correct answer. Does the equation below represent a relation, a function, both a relation and a function, or neither a relation nor a function?
y = x^2-9x

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.
