continuity is basically just if the graph isnt detatched at say.. an asymptote or if it jumps in a piecemeal graph.
there was a rule, that if:
lim f(x) = f(a)
x->a
that means it would be continuous at x = a
i dunno it made sense before.. then i went braindead hahaha. i'll go over it again, didnt go over it much today coz we were gonna rush out to find out prefects.
oh and if the limit looks like
x->^+
then x approaches a from the right, aka values larger than a. same goes with ^- but from the left.
yeah.. thats kind of it for today's maths notes
