Question 10 (1 point) 6 For what values of a and b will the function f(x) = ax' - x2 + bx -3 have a local maximum at x - 1 and a local minimum at x - -2? There are infinitely many such a, b pairs. There is more than one such a, b pair, but there is not infinitely many. Such an a, b pair is unique and satisfies a + b
