Question: 15)Given the quadratic function f(x) = -2X 2 +16 X - 24, use the process of completing the square to transform this function into vertex

15)Given the quadratic function f(x) = -2X2 +16 X - 24, use the process of completing the

square to transform this function into vertex form.

a) f(x) = -2(X - 4)2+ 8 b) f(x) = 2(X - 4)2 + 8

c) f(x) = -2(X - 4)+ 8 d) f(x) = -2(X - 4)2

16)Given the quadratic function f(x) = -2X2+16 X - 24, find the maximum value of f x for

all x. (HINT; use the process of completing the square to find the vertex form.)

a) f(x) = 8 b) f(x) = -8

c) f(x) = 0 d) f(x) = 4
