Answer 1

if you give an random answer and wait for the correction you'll not learn much. it's just an advice.

Answer 2

@dpaInc

Answer 3

okay, how about the inverse functions question up at the top. What do you know about doing such problems?

Answer 4

Not much, I did it earlier and got the answer A

Answer 5

Can you show me your work? That's not correct.

Answer 6

I just checked my work.....now Im getting B

Answer 7

Ah, that's better.

Answer 8

I cant type it all out, its complicated srry it would take forever

Answer 9

No, it's not that hard. y = 2x-4, solve for x:
\[y+4=2x\]\[\frac{y+4}{2}=x\]Swap variables:
\[y=\frac{x+4}{2}\]

Answer 10

My computer doesnt let me use the equation button :(

Answer 11

y+4=2x
(y+4)/2=x
Swap variables:
y = (x+4)/2

:-)

Answer 12

For 14. I got C

Answer 13

I don't do asymptotes. what's your next question?

Answer 14

15-17

Answer 15

15. I got D. 64

Answer 16

sorry, openstudy is being flaky for me this afternoon.

we can do the asymptote one. how are you going to identify the asymptotes from the equation?

Answer 17

I have no clue :(

Answer 18

Okay, what does it mean to have a vertical asymptote?

Answer 19

I worked it out with my tutor he got B

Answer 20

Let me ask a related question: does the function have a specific value at a vertical asymptote?

Answer 21

Here's another question: what is the value of that function at x=1 or x=-3?

Answer 22

Your tutor apparently needs some tutoring himself.

Answer 23

I really need the answers Im sorry normally I would work out the problems with you.

Answer 24

What, you think I have the answer sheet or something? If I'm going to work them out, you can work them out with me.

The vertical asymptotes happen wherever the denominator = 0 — they represent dividing by 0. Find the values of x where the denominator = 0 (remember: it is a product, so any of the components of the product can be 0 to make the product 0) and you've found the vertical asymptotes. They will be of the form x = <some constant value>.

Answer 25

Ok

Answer 26

Ill try that out. Ill give you my answer in a sec

Answer 27

The horizontal asymptotes are a bit trickier to think about, perhaps. They represent the horizontal line above or below which the function won't go. In this case, we have a division, so if the denominator gets really really big, the result of that division gets closer and closer to 0 (but never quite gets there). The horizontal asymptote will be of the form y = <some constant value>.

Answer 28

I got y=-3

Answer 29

wait no y=1
