Case study polynomial 2x^2 -4x+k when divided by (x+2) leave remainder -14 Find K II. Find the zero 

F(x) = 2x2 - 4 x + k, where k is a non-zero real number. When f (x) is divided by (x+2), it leaves a remainder of (-14).
I. Find K
II. Find the zeroes of f (x).
III. Shown below is the graph of f (x). the vertex is the minimum value of f (x) and the dotted line drawn through the vertex is the axis of symmetry of the graph.
At what point does the axis of symmetry intersect the x-axis?
IV. Find the minimum value of f(x).
