Problem 122 of 7
Identify the x-intercepts of the quadratic graph y=-x^2-4 and interpret them as zeros.
Hints
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Zeros occur where y=0.
2. Read graph crossings/touchpoints or solve factored equation.
3. State whether there are two, one repeated, or no real zeros.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Y-intercept as a zero.
