(c) on which interval(s) is the graph increasing? select the correct choice below and fill in any answer boxes within your choice.
Answer
Explanation:
Step1: Find x - intercepts
The x - intercepts are the points where the graph crosses the x - axis. From the graph, the x - intercepts are $(-\pi,0)$ and $(\pi,0)$.
Step2: Find y - intercept
The y - intercept is the point where the graph crosses the y - axis. From the graph, the y - intercept is $(0,0)$.
Step3: Determine the domain
The domain is the set of all x - values of the function. From the graph, the domain is $[-\pi,\pi]$.
Step4: Determine the range
The range is the set of all y - values of the function. From the graph, the range is $[-9,9]$.
Step5: Find increasing intervals
The function is increasing when the y - values are getting larger as the x - values increase. The increasing intervals are $\left[-\frac{\pi}{2},\frac{\pi}{2}\right]$.
Step6: Find decreasing intervals
The function is decreasing when the y - values are getting smaller as the x - values increase. The decreasing intervals are $\left[-\pi,-\frac{\pi}{2}\right]$ and $\left[\frac{\pi}{2},\pi\right]$.
Step7: Check for even/odd function
A function $y = f(x)$ is even if $f(-x)=f(x)$ and odd if $f(-x)=-f(x)$. Since the graph is symmetric about the origin, $f(-x)=-f(x)$ and the function is odd.
Answer:
(a) $(-\pi,0),(0,0),(\pi,0)$ (b) Domain: $[-\pi,\pi]$, Range: $[-9,9]$ (c) Increasing interval: $\left[-\frac{\pi}{2},\frac{\pi}{2}\right]$, Decreasing intervals: $\left[-\pi,-\frac{\pi}{2}\right],\left[\frac{\pi}{2},\pi\right]$ (d) Odd
