uestion 4 (2 points) The following quadratic function is in general form: f(x)=x^(2)-6x+13 Use the vertex formula to find the coordinates of the vertex. Express your answer with brackets but without any spaces. Coordinates of the vertex: A This quadratic function does not have real roots, but rather a pair of complex roots. The roots of f(x) take the form ^(a+-bi) where i is the imaginary unit. Use the quadratic formula to solve for the roots and input the values of a and b below. Both a and b are integers (no decimals). a= b=
