Answer 1

@nuts

Answer 2

ok, i want you to guess where to start

Answer 3

im alittle confused cause i dont know what to put for x

Answer 4

take a wild guess where to start :)

Answer 5

x2 − 7x − 9.
(-1)2-7(-1)-9

Answer 6

that's the right place to start c: what do you get?

Answer 7

\[-1^2 = -2\] right

Answer 8

noo (-1)^2=(-1)(-1)=1

Answer 9

ok so
1^2-7(1)-9

Answer 10

no :(
\( x^2 − 7x − 9; x=-1\)
\((-1)^2-7(-1)-9=?\)

Answer 11

i know but u said -1^2=1so i put
\[1-7(1)-9=\]

Answer 12

ok slow down there. (-1)^2=1.
-1^2=-(1^2)=-1
but, x=-1, so you need to be plugging in -1's for g(x) when you see x

Answer 13

=-1?
