Problem 128 of 7
Interpret graph x-intercepts versus complex roots for the quadratic function has x-intercepts at x=-3 and x=6.
Using a hint is okay. It just tells the trainer to give you a little more review.

Graph description must describe x-intercept behavior of a quadratic.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify x-intercepts as real roots.
2. Use touching versus crossing to detect repeated roots.
3. Remember a quadratic still has two complex roots counting multiplicity.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying no x-intercepts means no complex roots.
