What is the checklist when solving for limits?

Plug in number to f(x) > Done

0/0 > More work

#/0 > infinite limits

When determining a limit as x approaches 2, what must be true for it the be a valid limit?

F(x) must approach the same y value on each side for it to be valid

When can you use the nothing else matters method?

When the limit is approaching an infinity

When m>n how is the HA affected?

HA: y=0

When m<n how is the HA affected?

HA: NONE

When m=n how is the HA affected?

HA; y=an/bm

What is the checklist for continuities?

F(a) must be defined

lim_x>a f(x) must exist

f(a) = lim_x>a f(x)
