How many critical points does the functionf(x)=2sin2(3x)=2sin23have on the interval(0,)0,? Provide the x-coordinate for each of the first 2 critical points below in increasing order. Note that the interval does not include00or.

Include a multiplication sign between terms (e.g. 3*x). Type Pi for.

Number of critical points:

First critical point:

Second critical point:
