Please help with this problem. Thanks
a/ Show that for any real number x,
if x>1 then x^4=< 23x^4 + 8x^2 + 4x
b/ Show that for any real number x,
if x>1 then 23x^4 + 8x^2 + 4x => x^4
c/ Use the big Theta and big Onotations to express the results of part (a) and (b)
d/ What can you deduce about the order of 23x^4 + 8x^2 + 4x ?
