we know that
Even degree function
For an positive leading coefficient
if
f(x) -------> +infinite x -------> -infinite
f(x) -------> +infinite x -------> +infinite
OR
A -----> +infinite B -----> -infinite
A -----> +infinite B------> +infinite
Odd degree function

f(x) -----> +infinite x-----> + infinite
OR
A -----> -infinite B -----> -infinite
A -----> +infinite B ----> +infinite
