5) The graph of y = (2x - 4)(x - 4) is a parabola in the xy-plane (this is called factored form). Re-write the equation of the parabola in vertex form.

(A) y = 2x2 - 12x + 16
(B) y = 2x(x - 6) + 16
(C) y = 2(x - 3)2 + (-2)
(D) y = (x - 2)(2x - 8)

Hillel is juggling flaming torches to raise money for charity. his initial appearance raises $500\$500 $500 , and he raises $15\$15 $15 for each minute of juggling performance. the amount rr r of money hillel raises is a function of tt t , the length of his performance in minutes. write the function's formula.
