Question

Let f(x) = 24/3x -2 = . Find f(-2).
I think it's -3.
3(-2) -2 = -8
24/8 = -3
Am I right?

Answer 1

look: substitute -2 for x:
\[\frac{ 24 }{ 3 }*(-2)-2=8*(-2)-2=-16-2=-18\]

Answer 2

Can't be that, my choices are:
-6
-3
3
6
I chose -3.

Answer 3

oh i understood

Answer 4

your equation is 24/(3x-2)

Answer 5

\[\frac{ 24 }{ 3x-2 }\] Is the problem written like this?

Answer 6

24/(3x-2)=24/(-6-2)=24/-8=-3 correct then

Answer 7

Yes RKL, it is.

Answer 8

what you wrote @Tatsurion looked like \[\frac{ 24 }{ 3 }*x-2\]

Answer 9

Thank you. I'm having a lot of function difficulties and I need to make sure I get things right.

Answer 10

Okay then the answer will be 6.

Answer 11

How is it 6? I see no way that could happen unless you did the negative incorrectly.

Answer 12

If it as somehow a positive 4, then it would be 6.

Answer 13

\[\frac{ 24 }{ 3(2)-2 } = \frac{ 24 }{ 4} = 6\]

Answer 14

@Rkl36097 the function is -2 not 2

Answer 15

^

Answer 16

Hence why I said he did the negative wrong.

Answer 17

Answer 18

I am a guy and yes you guys are right I forgot about the negative. My bad.
