I am trying to input a problem; however I am unable to figure out how to enter the little circle that appears between (f ? g) (x).. It looks like the word fog; however the 0 is a little circle. Anyone know how to enter that into a formula for doing composition of two function?

OpenStudy (amistre64):

its just a lower case O (f o g)

OpenStudy (amistre64):

it means 'f' of 'g'

Actually there is a command for it. \circ or \bigcirc \[(f\circ g)\]

OpenStudy (anonymous):

\[(f\bigcirc g)\]
