Let function NoFontMessage () {} jsMath = {Parser: {prototype: {environments: {'eqnarray*' :['Array',null,null,'rcl',[5/18,5/18],3,'D']}}}}; g(x)=1/(x+2) Find the expression
g(x+h)-g(x) / h
this is what i did:
g(x+h)-g(x) / h
=g(x)+g(h)-g(x)/ h
=1/(x+2)+g(h)-1/(x+2) / h
=g(h) / h
= g
is this right?
