  1. There is no quadratic function which can have a vertex and axial intercepts where pictured.

    If we ignore the x-intercepts, the graph has form y=a(x+3)^2 +5. Using (0,-5) gives a=-10/9

    If, on the other hand we ignore the turning point the graph has form y=a(x+1)(x+5). Using (0,-5) gives a=-1.

    Which is close, but not the same as -10/9.

    Have I missed anything?
