f(x)= x^2+2x+10= 10/28/2013 | Bridget from Melbourne, FL | 2 Answers | 0 Votes Mark favorite Subscribe Comment Comments Hi Bridget; Are you looking for the maximum or minimum value? 10/28/2013 | Vivian L. Hello, Maximum is what I am trying to find 10/28/2013 | Bridget from Melbourne, FL Comment
Maximum value is infinity, since for very large x this function grows to infinity. 10/28/2013 | Kirill Z. Comment
Since the coefficient of the x^{2 }term is positive, this is the graph of a parabola opening upward toward +infinity. Vertex x = -b/(2a) = -2/(2)(1) = -2/2 = -1 y = f(-b/(2a)) = f(-1) = 9. Vertex (-1, 9) Minimum value would be 9. 10/29/2013 | Jason S. Comment
