Question

Given the function f(x) = 0.5|x – 4| – 3, for what values of x is f(x) = 7?
Yo this is timed so like...
THANKS!! WILL FAN AND MEDAL :*

Answer 1

x = –24, x = 16
x = –16, x = 24
x = –1, x = 9
x = 1, x = –9

These are the answer choices :)

Answer 2

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.

Answer 3

Answer 4

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

Answer 5

wow thanks! I probably should have thought of that haha, but thanks for the step by step =D

Answer 6

would you mind helping me with another? @Haseeb96

Answer 7

haha
okay i will do but after 10 mins
because first i have to help someone else
she hired me first. okay

Answer 8

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|

Answer 9

Sure thing!

Answer 10

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

Answer 11

Also the origin was at (0,0)

Answer 12

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

Sorry for tagging random... really need help it's timed haha

Answer 14

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.

Answer 15

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

Answer 16

-2/3 |x+4|-6 ***

Again, sorry for randomly tagging, ayudame por favor!!

Answer 18

Dudes, I got 6 minutes left on this timed thingy. PLEASE. I'll love you forever

Answer 19

I think for function , we get C is correct answer

Answer 20

okay, that's what i was thinking too thanks, what about the last question?

Answer 21

sorry idk for last one

Answer 22

that's okay thanks for all your help!!
