Answer 2

Never mind i have to go sorry

Answer 3

HI!!

Answer 4

we have to test them out

Answer 5

Hello, good to see you again. I was wondering if you could help here?

Answer 6

sure lets try \((0,0)\) which i know does not work
check if
\[0<0^2+4\times 0-4\] is true, but it is not since
\[0<-4\] is FALSE

Answer 7

I'm guessing we have to plug in the numbers into the x and y in the order of x and y, right?

Answer 8

But I do agree with 0,0 being wrong.

Answer 9

lets try \((-3,2)\)

Answer 10

So I put -3,2 into the other segments, right? So -3 into x^2 and 2 into x?

Answer 11

\[2<(-3)^2+4\times (-3)-4\]\ or
\[2<9-12-4\\
2<-7\] also false

Answer 12

So if I plug those in, they'll turn up wrong, so A and B are wrong ?

Answer 13

yes

Answer 14

So that leaves us with 1,5 or none of the above.

Answer 15

i think none of them work

Answer 16

\[5<1^2+4\times 1-4\\
5<1\] also false

Answer 17

So the answer would be none of the above, then?

Answer 18

i think so yes

Answer 19

Thank you, Misty.
