Find any relative extrema of the function. (Round your answers to three decimal places.) f(x) = arcsec(x) - 7x relative maximum (x, y) = relative minimum (x, y) = Solution Take the derivative of the function f\'(x) = 1/(x(x2-1)) - 7 set it equal to 0 and solve for x x4-x2 = 1/49 x=[1±(1-(4)(1)(-1/49))]/2 = (1±(53/49))/2 = 1.020 and -.020 pick values on each side of each value of x and plug into the derivative to see whether the function is increasing (derivative is +) or decreasing (derivative is -). If it is increasing on one side and decreasing on the other, then the point is a max and vice versa..
