    Stuck on quadratics chapter review question

    the equation of curve b is y=-6+4x-x^2 (h, 3) is the vertex of a parabola A, with equation y=x^2+b+c. Find the values of b,c and h for h>0
    B) let P be a point on curve A and P' be a point on curve B such that PP' is perpendicular on to the x axis.

    i will just send a photo is that ok?

    could you also help with the next question as well, not trying to be desperate here but step by step please for both questions question 11 picture

    Forgotten

    Look at the graph of the unknown curve A it intersects the y-axis at (0,4) this means that C is 4.
    also the line of symmetry of any parabola expressed in the quadratic form y=ax^2+bx+c is x= -b/2a this is equal to h in your case...
    the rest is easy ..try to do some homework on your own.
