Fill in the blanks so that the resulting statement is true. The quadratic function f(x) = a(x - h)2 + k, a #0, is in form. The graph of f is called a whose vertex is the point The graph opens upward if and opens downward ifFill in each blank so that the resulting statement is true. Consider the quadratic function f(x) = ax"+ bx + c, a #0. If a > 0, then f has a minimum that occurs at x = This minimum value is If a 0, then f has a minimum that occurs at x = This minimum value is |If a
