Which equation of f(x) reveals the minimum or maximum value of f(x) without changing the form of the equation? A. f(x)=x^2- 2x - 4x+8
B. f(x)= (x-4)(x-2)
C. f(x) = (x - 3)^2-1
D. f(x) =x^2-6x+8

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
