Answer:

y = 100

Step-by-step explanation:

y [tex]\alpha[/tex] [tex](x -1)^{2}[/tex]

y = c ([tex]x^{2}[/tex] - 2x + 1)

When y = 63, x = 4;

63 = c ([tex]4^{2}[/tex] - 2(4) + 1)

     = 9c

63 = 9c

c = [tex]\frac{63}{9}[/tex]

c = 7

Thus,

y = 4([tex]x^{2}[/tex] - 2x + 1)

The value of y when x = 6 can be determined as;

y = 4([tex]6^{2}[/tex] - 2(6) + 1)

   = 4(25)

y = 100

Therefore, y = 100
