How to convert the definition into one of the following limit definitions

To be clear: Each definition corresponds to one of the listed limit definitions

Definition 1:

For any M here is an N such that when xM

Definition 2:

For any M here is an N such that when x>N we get f(x)

Limit Definitions:

lim f(x) as x->a = infinity

lim f(x) as x->a = -infinity

lim f(x) as x->infinity = L

lim f(x) as x->-infinity = L

lim f(x) as x->infinity = infinity

lim f(x) as x->infinity = -infinity

lim f(x) as x->-infinity = infinity

lim f(x) as x->-infinity = -infinity

lim f(x) as x->a+ = infinity

lim f(x) as x->a+ = -infinity

lim f(x) as x->a- = infinity

lim f(x) as x->a- = -infinity
