Question 10 6 points How Did I Do? How many critical points does the function f (x) = 8sin (7x) have on the interval (0, )? Provide the x- coordinate for each of the first 2 critical points below in increasing order. Note that the interval does not include 0 or . Include a multiplication sign between terms (e.g. 3*x). Type Pi for . Number of critical points: Number First critical point: a sin (a) Second critical point: ab sin (a)
