What can you say about the inflection points of a quadratic curve y= ax + bx+c, a#0? Give reasons for your answers. The curve (1) because y'' (2) does not exist. (1) O does not have any inflection points has an inflection point at x = 0 b has an inflection point at x = - 2a is constant. changes sign at that point. Find the values of constants a, b, and c so that the graph of y = ax + bx² + cx has a local maximum at x = - 1, local minimum at x = - 3, and inflection point at (-2,2). a= C= b= (Simplify your answers. Type integers or simplified fractions.)
