Problem 85 of 7
Connect complex solutions to graph feature parabola opens upward and stays above the x-axis.
Using a hint is okay. It just tells the trainer to give you a little more review.

Walkthrough
Full solution stays hidden until you ask for it.
1. Determine whether the graph crosses the x-axis.
2. X-intercepts correspond to real solutions.
3. If there are no x-intercepts, non-real complex roots occur for a real-coefficient quadratic.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying complex roots are visible x-intercepts.
