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

thanks heaps.
