Asked by Sgt peppers

how do you graph a polynomial function such as f(x)= 1/10(x=3)(x-1)(x-4)?

I know that I need to fing the x intercepts, End Behaviors, and, the turning points but i cannot figure out how to even get thosee. Please help.

YOu get the zeroes by setting f(x)=0.

zeroes are at x=-3, 1, 4
What is f(x) at x= inf?
What is f(x) at x=-very large?

Sorry, I'm still confused. How do you get from f(x)=0 to -3, 1 and 4.

what are the steps needed to solve this?
Answered by Damon
when for example x= 4
then
f(x) = something * (4-4) = 0
