Answer

Explanation:

Step1: Identify range from graph

The lowest - y value is - 6 and the highest is 6.

Step2: Write in interval notation

The range is all y - values between - 6 and 6 inclusive. So the range is $[-6,6]$.

Step3: Identify increasing intervals

The function is increasing when the graph goes up as we move from left to right. From the graph, it is increasing on the interval $\left(-\frac{\pi}{2},\frac{\pi}{2}\right)$.

Answer:

(a) x - intercepts: $x =-\pi,0,\pi$; y - intercept: $y = 0$ (b) Domain: $[-\pi,\pi]$, Range: $[-6,6]$ (c) Increasing interval: $\left(-\frac{\pi}{2},\frac{\pi}{2}\right)$ (d) The function is odd since it is symmetric about the origin.
