Question 14: (3 points) Let f (x) = sinc. Determine the x-value(s) where the function has a maximum or minimum value on [0, 27). To enter 7, type Pi (with a capital P) The fields below accept a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or x + 1; x - 1). The order of the lists do not matter. On [0, 271), the maximum value(s) of the function occur(sat what a-value(s)? On [0, 271), the minimum value(s) of the function occur(s) at what x-value(s)? C =
