Problem 4 of 7
Identify the mathematical domain of quadratic function p(x)=0.5x^2.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
recognize unrestricted real-input domain.
Hidden until you reveal it.
Function must be a polynomial quadratic with no contextual restrictions.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Recognize the function is a polynomial.
2. Polynomial expressions are defined for every real input.
3. State the mathematical domain as all real numbers.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Restricting domain because of graph shape when no context is given.
