what does gog(n) represent to you?

worldly stratus
#

g(g(n))

#

g(n) = n-2
so g(g(n)) = g(n-2)
After this i dnot understand how I can get to the answer n-4?

thorny snow
#

what is g(x) now?

worldly stratus
#

g(n-2)

thorny snow
#

nono, in terms of x

worldly stratus
#

uuh...

thorny snow
#

g(n)=n-2 remember

#

so g(x)=?

worldly stratus
#

0?

thorny snow
#

no

#

i think something is fundamentally holding you back from doing operations like these

#

what do you think is "illegal" in this context (i.e. what do you think you can't do)?

worldly stratus
#

I dont understand how g(g(n)) = g(n-2) becomes the answer n-4

thorny snow
#

i know

#

that was my point of doing g(x)

#

like, we know g(n)=n-2

#

g(x) is simply a change of variables

#

so g(x)=?

worldly stratus
#

wait

#

so

#

g**(g(n))** = g(n-2) this is highlighting only the thing in bold

#

Now you are bringing in the not bold g(x)to g(x)g(n))

#

right?

thorny snow
#

is that a typo

worldly stratus
#

uh nope

thorny snow
worldly stratus
#

im just wondering where u got x from and where you would put that into the g(g(n))

#

x would be x-2?

thorny snow
#

so g(g(n))=g(x)=?

worldly stratus
#

oh

#

g(n-2)=n-2

#

or g(n-2)-n-2?

#

can we get on call...

thorny snow
#

i just cant speak

worldly stratus
#

sure ok thatll do

thorny snow
#

can u see it?

#

?

#

what did u say

worldly stratus
#

g(g(n)) = n-2
g(g(n)=g(x) = g(n-2) = g(-2) = g(n-2)-2 = g(n-4)??

thorny snow
#

no

#

remember you want to get a closed form of g(x) before subsituting x=n-2

#

so we know that g(n)=n-2

#

g(x)=?

worldly stratus
#

(n-2)-2

#

actually g(x) = x-2

#

I guess im going to flop

thorny snow
thorny snow
worldly stratus
#

so g(x) = x-2 and we substitute it in giving us (n-2)-2?

worldly stratus
#

btw could you help me with anything related to computer science?

worldly stratus
#

ah i do have this on my slide...

#

🤦🏽‍♂️

#

thanks for the help bro
