[sand tree]

have you seen this notation

$f \circ g$

[west dome]

Ephesians 2:8-9

[sand tree]

have you ever seen that circle

[vapid thistle]

i have not seen this

[clever temple]

Oh, is that what it's supposed to be? I thought it was supposed to say "g of x".

[vapid thistle]

what does O mean

[sand tree]

it's poorly written

[vapid thistle]

o meaning?

[sand tree]

but it only makes sense if it's a composition function

[clever temple]

f o g(x) = f(g(x))

[vapid thistle]

okay so O is ue to interpret like that?

so it is g(f(x))

[sand tree]

correct

[vapid thistle]

not f(g(x)

[sand tree]

correct, g(f(x)) in your case

[vapid thistle]

what is O to be specific

[sand tree]

I'm not sure what you're asking

it's a shorthand way to write g(f(x))

[vapid thistle]

ok

o i shorthand

is*

[sand tree]

o is a symbol which represents a composition function

$f \circ g = f(g(x))$

[west dome]

Ephesians 2:8-9

[vapid thistle]

ok

[sand tree]

$f \circ f = f(f(x))$

[west dome]

Ephesians 2:8-9

[sand tree]

$g \circ f = g(f(x))$

[west dome]

Ephesians 2:8-9

[vapid thistle]

dat was fookin easy

[sand tree]

yeah, just written poorly

they didn't use the symbol and added a weird space

making it kinda hard to understand what they're asking for exactly

hope that helps

[vapid thistle]

thanks
