Problem 62 of 7
Identify where quadratic model g(x)=-(x+2)^2+5 is increasing and decreasing.
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. Identify the vertex x-coordinate.
2. Use opening direction to see behavior on each side.
3. State increasing and decreasing intervals.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Reversing intervals for upward versus downward opening parabolas.
