Express y = 5 - 2x - 4x2 in the form y= A - B(x + C)2, where A, B and C are
constants. Hence state the maximum value of
the function f:x → 5 - 2x - 4x2.​

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option

step-by-step explanation: w

f(x)=2/3x-8, which give g(x) the greatest value.
