I'm doing an online course, and am finding it to be extremely difficult to do without having an actual teacher that you can sit with and a classroom full of others you can work with. 1. One of the questions is: Determine a general equation for the quartic function f(x) as described: f(x)<0 when x< -2, f(x)>0 when -2<x<3, and f(x)<0 when x>3, the zeros are -2, -1, and 3. I've never worked with quartic functions or anything like this. If anyone has some guidance that would be fantastic!!!
