Write the equation of the parabola in vertex form. vertex (2,4) point (1,1)

Answer 1

Please note that the directorix is not stated so I assumed the standard form of y-k=4p(x-h)² where h,k is the vertex 2,4. Thus y-4=4p(x-2)². To find p, use the given point 1,1 and solve for p = -3/4. The final form is y-4=-3(x-2)².
