Refer to the description.

Explanation:

Given,
f(x)=sin2x
Recall that the range of sine is [1,1] . Since the function is squared all the negative values are reflected positive. So it must lie in 1st and 2nd quadrant. It only passes through the y axis and is tangent to x axis because at x=0 and x=kπ
