Can anyone formulate 5.3.2 and 5.3.4? I am having difficulties with these problems. I'm not sure what to do for 5.3.2 either.
For #4 your can let p(x)=a(x)^n where n is odd and a is a coefficient.
Then by 4.3.16 limp(x) as x-inf =inf and lim(p(x)) as x= -inf = -inf
thus there exist x, such that p(x)>0 and x such that p(x)<0 then you can use the Root thereom.
