the set of zeroes of the function f where f = x2-x-2/x2-4 is ................................
+37156 Factor the numerator: (x-2)(x+1) leads us to BELIEVE that x = 2 and x = -1 are zeroes
BUT looking at the denominator x cannot equal 2 (cannot have a value of zero in the denminator)
so the only zero left is at x = -1
+2 Just wanted to let you know that writing service also can manage problem solving type of work just as multiple choice questions.
