Question

which choice describes the domain of a quadratic function?

all of the y-values that are possible within the function.

all of the x-values that are possible within the function.

Explanation:

Define the concept of domain

The domain of any mathematical function is the complete set of all possible input values (typically represented by \(x\)) for which the function is defined and produces a real output.

Analyze the given options

• The first option describes "All of the \(y\)-values that are possible within the function," which is the definition of the range.
• The second option describes "All of the \(x\)-values that are possible within the function," which is the definition of the domain.

Answer:

• All of the y-values that are possible within the function.
• All of the x-values that are possible within the function. (Correct answer)
