Show that the equation x" - 11x + 1 =0 has three solutions in the interval [ - 4, 4]. Let f(x) be equal to the left side of the equation. Where do the solutions to the equation exist? O A. Solutions exist at values of x, and x, if 0 s f(x, ) f(x2). O B. Solutions exist between values of x, and x, if f(x, )50 and f(x, ) =0 or f(x, )20 and f(x2 ) 20. O C. Solutions exist at values of x, and x, if f(x, ) f(x2)- D. Solutions exist between values of x, and x, if f(x, )50 and f(x,) 20 or f(x, ) 2 0 and f(X2) =0. Find f( - 4). f( - 4) = (Simplify your answer.)
