Question

From the graph of $sin2x$, the period and range will be

• A. Range$=[-1,1]$, Period$=2\pi$
• B. Range$=[-1,1]$, Period$=\pi$
• C. Range$=[-1,0]$, Period$=\pi$
• D. Range$=[0,1]$, Period$=2\pi$

Answer 1

The correct option is B Range$=[-1,1]$, Period$=\pi$

If we draw the graph, we can easily find out the range and period of the function.

Range$=[-1,1]$, Period$=\pi$
