Problem 146 of 7
Graph polynomial f(x)=(x^2+4x+5)(x-1)(x+3) while excluding nonreal roots from x-intercepts.
Using a hint is okay. It just tells the trainer to give you a little more review.

use real zeros only for graph crossings.
Hidden until you reveal it.
Use real zeros only for graph crossings; irreducible quadratic factors do not create x-intercepts.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Factor over the reals if possible.
2. Identify which factors produce real zeros.
3. Use only real zeros as x-intercepts on the graph.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Plotting x-intercepts from factors with no real zeros.
