Answer 1

@jim_thompson5910

Answer 2

this is the function?
\[\Large f(x) = \frac{-x^2-2x-2}{x-2}\]

Answer 3

yes! @jim_thompson5910

Answer 4

ok so you'll type in

`(-x^2-2x-2)/(x-2)`

into something like

https://www.desmos.com/calculator

Answer 5

make sure you zoom out so you can see the whole graph

Answer 6

so when i type that in that is indefinitely my graph visually? @jim_thompson5910

Answer 7

there are 2 (disconnected) branches

Answer 8

yeah that's what the graph looks like

Answer 9

two of my answers from my choices look similar but aren't the same

Answer 10

@jim_thompson5910

Answer 11

how are they different?

Answer 12

@jim_thompson5910 they are a tad different

Answer 13

can you show me?

Answer 14

yea @jim_thompson5910

Answer 15

ok post a screenshot please

Answer 16

sorry I'm getting it

Answer 17

that's ok, take all the time you need

Answer 18

here is the one that i think is correct

Answer 19

would you say the same?

Answer 20

When i use the equation i dont get that

Answer 21

what do u get?

Answer 22

@hippo211

Answer 23

could you draw the graph

Answer 24

@iwanttogotostanford what does the other graph look like?

Answer 25

ok, ill give the answer choices and graphs

Answer 26

ok

Answer 27

A.

Answer 28

B.

Answer 29

C.

Answer 30

D.

Answer 31

if you plugged in x = 0, what would the value of f(0) be equal to?

Answer 32

which of the graph choices would you say it is?

Answer 33

\[\Large f(x) = \frac{-x^2-2x-2}{x-2}\]

\[\Large f(0) = \frac{-(0)^2-2(0)-2}{0-2}\]

\[\Large f(0) = \underline{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }\]

fill in the blank

Answer 34

i got -2/-2 but i think i did my algebra wrong

Answer 35

-2/-2 will reduce to 1

Answer 36

so f(0) = 1

this means that the point (0,1) is a point on the graph of f(x)

Answer 37

yes, true

Answer 38

so use desmos to graph

and use the fact that (0,1) is on the graph

Answer 39

so B would be the closest answer, correct?

Answer 40

did you use desmos to graph?

Answer 41

yess

Answer 43

now i am thinking C or D?

Answer 44

thats in wrong the way you enter the info

Answer 45

look at this

Answer 46

I'm very confused about which one it would be people

Answer 47

A, B, C or D??you both are saying different answers

Answer 48

@hippo211 I think the first negative only applies to the x^2 (not the whole fraction)

Answer 49

look at how I wrote out f(x) in my first post

Answer 50

@jim_thompson5910 yes, true the negative i only applied to that

Answer 51

so would it be C or D

Answer 52

really need confirmation here

Answer 53

look at the answer choice that goes through (0,1)

Answer 54

oh ok i see now yes your right

Answer 55

i honestly can't tell from the graphs @jim_thompson5910

Answer 56

0,1 i would think A @jim_thompson5910

Answer 57

it can't be A because the lowest point on the left branch is somewhere in Q2

Answer 58

im so confused though did you look at the graphs i attached ?

Answer 59

yes I did

Answer 60

in choice A, the lowest point on the left upper branch is somewhere in Q1

when it should be somewhere in Q2

Answer 61

the graph looks like this
