Hi, new here.
I was wondering how can you get a fourth degree polynomial with a graph that only has 1 turn?
This is the problem: 5x^4 +15x^2 + 10
I thought the number of turns (or "bumps" as my teacher calls them) could be determined by "n-1"; n being the exponent of the leading coefficient. So, I thought this questions should have 3 turns, because 4-1= 3.
(Hope I used the correct names for things here. I usually get confused with math terminology.)
