Simplifique esta solución The Deep Dive
To determine where the function
First, the derivative
Using the quadratic formula,
After applying the formula, we find the critical points, and then test the intervals around these points to find where the derivative is positive (indicating increasing behavior) or negative (indicating decreasing behavior).
By evaluating the derivative around the critical points, we discover that:
- The function is increasing on the interval(s):
. - The function is decreasing on the interval(s):
.
So here’s how you might fill in your answer:
A. The function is increasing on the interval(s)
A. The function is decreasing on the interval(s)
Now, let’s sprinkle in some extra knowledge!
The polynomial function you peeked at has a lot of character! It’s shaped like a roller coaster, creasing and dipping around its critical points. So, every time you analyze it mathematically, imagine it feels those ups and downs—like an adventure ride in the world of functions!
If you’re intrigued by more complex functions, you could dive into topics like calculus of higher-order derivatives or even explore how these principles apply to real-world scenarios like optimizing profit in business or modeling population dynamics in biology—understanding those curves can really help you navigate the twists and turns of life!
