Answer 1

whatcha need

Answer 2

what does (A ∩ B) ∪ (~A ∩ C) mean?

Answer 3

no idea

Answer 4

not extremely helpful. @Dobby1

Answer 10

Given the function g(x) = 8x − 2, compare and contrast g(−2) and g(4). Choose the statement that is true concerning these two values.

The value of g(−2) is larger than the value of g(4).

The value of g(−2) is the same as the value of g(4).

The value of g(−2) is smaller than the value of g(4).

The values of g(−2) and g(4) cannot be compared.

can you help with this one. I am no good at this type of thing.

Answer 11

This is... an entirely different question now...

Answer 12

I know. i am doing a math test and these are the two i am stuck on. i do not want answer oly for you to help explain them both.

Answer 13

@terenzreignz are you gonna help?

Answer 14

OS is incredibly slow for me...
I was asking if perhaps you can post the choices for this:
(A ∩ B) ∪ (~A ∩ C) ?

Answer 15

Here's a good link to explain the "U" symbols. http://en.wikipedia.org/wiki/List_of_mathematical_symbols

Answer 16

∪ means "OR", ∩ means "AND", I believe

Answer 17

I think "~" means "NOT", but that's a guess for me

Answer 18

I solved that one. I had to watch a bunch of tutorials online for it. Sorry.
can you help with the other one. @MichelCarroll

Answer 19

g(x) = 8x - 2

To find g(-2) and g(4), simply replace the x in "8x - 2" with -2 and 4, respectively.

Answer 20

how would i solve that. I really do not know how to do it. Please just give me the steps.

Answer 21

Okay, a few examples, perhaps?
We have
g(x) = 8x - 2
Let's say we have to find g(3)
Then we replace the x in the function with 3... like so:
g(3) = 8(3) - 2
Simplify...
g(3) = 24 - 2
g(3) = 22.

Another: say we need g(-1)
As in the first example, replace x with -1... like so:
g(-1) = 8(-1) - 2
Simplify again...
g(-1) = -8 - 2
g(-1) = -10

Having said that, can you now find g(-2) and g(4)

Answer 22

for g(-2) it is 9 correct?
i am starting on the other.

Answer 23

g(4) is going to end up g = 7.5?

Answer 24

No, it's not. Try again, replace x with -2...

Answer 25

8x-2 is -16

Answer 26

that is true... so how did you end up with 9?

Answer 27

subtract 2 and you get -18.
i divide by -2 and got positive nine.

Answer 28

Why did you divide by -2?

Answer 29

As I recall, g(x) = 8x - 2
there is no division by -2 involved... is there?

Answer 30

would i multiply. i thought you divided to get g.

Answer 31

ahh, I see LOL

Answer 32

Here's the problem...
\[\Large g(x) \color{red}\ne g\cdot x\]
g(x) is not g multiplied by x :)
It's confusing at first, but you'll get it in time...

Answer 33

what do you mean. what is g x?
would my final answer be g(-2)=-18
and the other one be g(4)=30

Answer 34

Yes. Exactly :D

Answer 35

So, now that you know what g(-2) and g(4) are, I guess the answer to your question should be easier to get? :)

Answer 36

"you are doing a math test" is not a good thing to post on here .....

Answer 37

so my final answer to the problem is going to end up being c

Answer 38

I am asking for help. i only wanted to learn how to do it so i can finish the test. I see nothing wrong with having help figuring it out. nobody has told me answers and i do not want them.

Answer 39

i understand that, but there are affiliations that check this site to determine if their students are using it contrary to their own codes of conduct.

its would simply be best if you did not provide that information is all .....

Answer 40

thank you @terenzreignz for helping me. that is all i did not understand.
Thanks @amistre64 for telling me that. i honestly just thought you were annoyed i was asking for help on an exam. lol

Answer 41

'sok :) i just dont want to have to enforce our own policy on someone who is not really trying to cheat is all

Answer 42

good luck

Answer 43

Good luck :)
