Question

Given the graphed functions below which of the following ordered pairs are found on the inverse function?
A.(-10,-2),(-3,-1),(-2,0),(-1,1),(6,2)
B.(2,10),(1,3),(0,2),(-1,1),(-2,-6)
C.(10,2),(3,1),(2,0),(1,-1),(-6,-2)
D.(-2,10),(-1,3),(0,2)(1,1),(2,-6)
Please Help Me Out :(!

Answer 1

what is the function ?

Answer 2

@satellite73

Answer 3

dang harder than i though
is \((-2,-10)\) on the graph of that function you posted?

Answer 4

@satellite73 i have no idea on what your asking me :( im new to all this and its really stressful to me :/!

Answer 5

ok lets go slow

Answer 6

find \(-2\) on the \(x\) axis
let me know when you see it

Answer 7

did you find \(-2\) on the x axis?

Answer 8

yes i did ! @satellite73

Answer 9

ok now go straight down to the curve from the point -2 on the x axis
what is the y coordinate there?

Answer 10

@satellite73 -10?

Answer 11

yes
so the answer to my question "is \((-2,-10)\) on the graph?" is YES

Answer 12

now here is what you need to know: if \((-2,-10)\) is on the graph of \(f\) then ((-10,-2)\) is on the graph of \(f^{-1}\) you switch them

Answer 13

@satellite73 so the answer will be A?

Answer 14

well that first point checks out, we need to check more

Answer 15

darn lol @satellite73 sounds good lets check
more then

Answer 16

is \((-1,-3)\) on the graph of \(f\)?

Answer 17

left one, down 3, are you on the curve?

Answer 18

@satellite73 yes im on the curve

Answer 19

ok that means, since \((-1,-3)\) is on the graph of \(f\) we know \((-3,-1)\) is on the graph of \(f^{-1}\)

Answer 20

two points good

Answer 21

yes check! @satellite73

Answer 22

ok how about \((0,-2)\)?

Answer 23

nope but i see -2,0? @satellite73

Answer 24

no you got them backwards
if x = 0 then y = -2 meaning \((0,-2)\) is on the graph of \(f\) and \((-2,0)\) is on the graph of \(f^{-1}\)

Answer 25

oh ok i see now sorry @satellite73

Answer 26

ok i am done torturing you
looks like all of A is good

Answer 27

wasn't that stressful was it ?

Answer 28

omg it was correct thank you! and nope now it isnt thank you so much! it really means alot! @satellite73

Answer 29

you are quite welcome
you have any more stressful ones?

Answer 30

yeah one more! @satellite73

Answer 31

@satellite73

Answer 32

you are being asked to check the "horizontal line test"
if any horizontal line intersects the curve at most one, then yes
if it intersects more than once then no

Answer 33

@satellite73 well it looks like it just curves one time? am i correct?
