according to the fundamental theorem of algebra, which polynomial function has exactly 8 roots?
(1) f(x)=(3x^2-4x-5)(2x^6-5)
(2) f(x)=(3x^4+2x)^4
(3) f(x)=(4x^2-7)^3
(4) f(x)=(6x^8-4x^5-1)(3x^2-4)
so im a bit stuck on this one,A and B. i have gotten 2 very different answers from my fellow classmates, so im coming here to hopefully settle this. how do i go about solving this one? as much detail as possible i really need to have this down befoer the exam next week. also what is a good form of mapping simply (x,y)--> (x\sqrty)? im always unsure how i should state my mapping.
Prove each identity. show your steps please, i want to make sure i got it all correct. I was going to post my work but apperantly you cant attach files anymore? the biggest thing is im not sure how to express the non-permissible values or how to find them im really weak in that area.
