Find the values of x that give critical points of y=ax2+bx+c, where a, b,c are constants. under what conditions on a, b,c is the critical value a maximum? a minimum? enclose numerators and denominators in parentheses. for example, (a−b)/(1+n). x= use the drop-down menus to indicate whether the critical value is a maximum or a minimum under certain conditions. the critical value is a :
