Answer 6

Yes I do. It's foil right?

Answer 7

thats not multipication

Answer 8

what isnt?

Answer 9

That reads as
"f of g of -5"

Answer 10

Oh ooops!

Answer 11

That means for every x in the equation f(x) you plug in g(-5)

Answer 12

so g(-5)=?
then F(g(-5))
2(g(-5))+1

Answer 13

g(-5) is -5g

but I'm lost on the next part tho

Answer 14

g(-5) isnt -5g
g(-5) reads as g of -5
This means that for every x in g(x), you plug in -5

Answer 15

g(-5) isnt -5g
g(-5) reads as g of -5
This means that for every x in g(x), you plug in -5

Answer 16

ohhh!

so 2(-5) +1
and -5^2 ?

Answer 17

nevermind not right lol sry i'm dumb, but just for g(x)?

Answer 18

yes, then plug that answer in for f(x)

Answer 19

So 2(-25)+1?

Answer 20

which is 51

Answer 21

yes, but from what you wrote, you had 2(-25)
it should be 2(25) because a negative times a negative or squared equals a postive
since you did get 51, i assume that was just a typo.

Answer 22

Yes it was, thank you!
