Q: How do you hand-graph an equation like this:
f(x) = 3x^3 + 4x^2 - 3x + 1
Or any equations like that. We learned how to do it in Alg II last year, but the problem is that I don't know how to do it by hand at all & I can't find the notes on it. Our teacher gave us a pre-test type thing to our class to see where we were and one of the questions asked to graph an equation similar to that and to make sure all the points were indicated clearly on the graph. Well, I plugged it into my calculator, but I didn't know where to put the points at all, so I completely missed.
So, my questions are how do you hand graph an equation like that. And if you put it in your calculator, how do you know where to put dots on a graph on a paper? Thanks!
