Answer

The next positive x-intercept is $~~x = 3.464$

Work Step by Step

The least positive x-intercept of the graph of this function is $x = 0.322$ Since the period of this function is $\pi$, we can find the next positive x-intercept. $x = 0.322+\pi = 3.464$ The next positive x-intercept is $~~x = 3.464$
