Does the value of c in the quadratic function y = ax2 + bx + c affect the vertical position of the vertex of the graph? Explain
why or why not. A. No; the position of the axis of symmetry and hence the vertex point is affected only by the values of a and b.
B. Yes; changing the value of c shifts the entire graph, including the vertex point, up or down.
C. No; changing the value of c shifts entire graph left or right. It does not affect the vertical position of the vertex.
D. Yes; increasing c shifts the vertex point down.
