I need assistance with these... thank you so much!

What is the slope of the tangent line to the graph of any quadratic function of the form (given below) at its vertex? a, b and c are constants * y = ax + bx + c O equal to the y-coordinate of the vertex equal to the x-coordinate of the vertex Oo OI 6 Using the limit definition of the slope of the tangent line to the function f (given below) at x=2, which of the following is the correct initial solution? * [ f (x) = x - 7x O m (2) = limp-. (23-7(2))-[(2+4)-7(2+h)] O m (2) = limp-o [(2+4)3-7(2+1)]-(23-7(2)) O m (2) = limp-20 [(2+A)3-7(2)]-(23-7(2)) From the given, which of the following statements is FALSE? a = 0; [0,2) f ( x) = 3 - x2 if x>0 2x +3 if x
