How many critical points does the function f (x) = 4sin (6x) have on the interval (0, 7)? 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 TT. Include a multiplication sign between terms (e.g. 3*x). Type Pi for . Number of critical points: Number First critical point: ab sin (a) ? Second critical point: sin (a)Find the absolute maxima for the function: f (x) = 2 x + sin (2 x) on the interval [0, 2 x]. Enter the exact answers. va al sin (a) absolute maximum = /a al sin (a) absolute minimum =
