    x = –24, x = 16 x = –16, x = 24 x = –1, x = 9 x = 1, x = –9 These are the answer choices :)

    I already tried plugging in the answer choices into the equation, but none of them turned out to answer 7. I just want to know what I'm doing wrong.

    now what you will do we will put 7 at the place of f(x) in the given equation . it will be look like this 7 = 0.5 Ix -4I - 3 7 +3 = 0.5 Ix-4I 10 = 0.5 Ix-4I 10/0.5 = Ix-4I 20 = -(x-4) -x +4 =20 -x = 20 -4 -x = 16 x= -16 is your answer

    Which function is a translation of the parent absolute value function? f(x) = 2|x| f(x) = |x+6| f(x) = |x| f(x) = -4|x|

    I'm thinking it's either A or C. Probably C, because it came out the most normal looking when I graphed it. lol

    ooohhh wait it says translation. so this must mean flipped over an axis, but it doesn't say which one?? I'm probably not making any sense, but just wanted to explain my thought process. haha

    Which statement is true about -2/3 |x+4-6? The graph of f(x) has a vertex of (–4, 6). The graph of f(x) is horizontally stretched. The graph of f(x) opens upward. The graph of f(x) has a domain of x (less than or equal to) –6.

    That one is also confusing... I think I just suck at absolute value functions
