the following graphs show one period of a periodic function. answer any questions that follow. is the function increasing, decreasing, or both on the interval 45 < x < 51? is the function concave up, concave down, or both on the interval 12 < x < 18? is there a relative max, relative min, or neither at x = 33?
Answer
Explanation:
Step1: Analyze increasing - decreasing
For the interval $45 < x < 51$, as $x$ increases, the $y -$ values of the function are decreasing.
Step2: Analyze concavity
For the interval $12 < x < 18$, the function curves upward, so it is concave up.
Step3: Analyze relative extrema
At $x = 33$, the function is neither at a peak (relative max) nor at a trough (relative min).
Answer:
- Decreasing
- Concave up
- Neither
