Consider the function f(x) = 18x -7 sinc . Find the critical number(s) of f in the interval [-1, 1). Find the values of z in the interval [-1, 1] at which the function attains its absolute maximum and absolute minimum values. Note: Write the exact answer not the decimal approximation (for example, write 1/2 but not 0.5). If the answer has a squre root then use the equation editor or use parentheses, for example, for : 3 write (3)(1/2) do not write (3)~{1/2} or (3)*[1/2]. Answer. There are Click for List critical numbers of f in the interval [-1, 1] The absolute maximum of the function f occurs at = = The absolute mimnimum of the function f occurs at r
