Determine the vertex of y=4(x-25)2+ 91

Step-by-step explanation:

y = a(x - h)² + k        ← vertex form of  the equation of the parabola with vertex (h, k)

So y = 4(x - 25)² + 91  means:

a = 4

x - 25 = x - h    ⇒  - 25 = - h  ⇒  h = 25

+ 91 = + k     ⇒    k = 91

Therefore vertex is:

                               (25, 91)
