Answer 5

Try this

Answer 6

hmm @Vocaloid can you put some input to this?

Answer 7

the x-coordinates need to be distinct

Answer 8

so b

Answer 9

im thinking either B or A

Answer 10

B is correct

Answer 11

notice how A has x = -4 twice

Answer 12

Ohh yes

Answer 13

Answer 14

are these correct? ^

Answer 15

but why is that? @Vocaloid

Answer 16

check question 2

when you take the inverse, switch the x and y coordinates

so you get

(-6,-3) (2,-1) (2,1) (6,3)
is this a function or not? @Nicole

Answer 17

No because theres 2 multiple times

Answer 18

good, since x = 2 appears with two different y-coordinates the inverse is not a function
making question 2 true

Answer 19

question 3 is correct

Answer 20

Got it

Answer 21

apply the horizontal line test

if you can draw any horizontal line that crosses the function multiple times, then the inverse is not a function

otherwise, it is

Answer 22

No so it would be false

Answer 23

wait no it would be true

Answer 24

be careful
there's no horizontal line that crosses the function multiple times so the inverse ***is*** a function

Answer 25

Yes I figured

Answer 26

careful about question 7
that red circle is closed so the function does include x = 1

Answer 27

Oh so A

Answer 28

one more thing

the function is all values **greater*** or equal to 1, so x >=1

Answer 29

Ohh okay makes sense

Answer 30

8 and 9 are good
for question it says to add them
3x + 2x + 5 - 9 =

Answer 31

also check 11 again

2x * (1/2) =

Answer 32

rest are good
