for the function f(x) = (x-4)(x+1)(x-1)

the domain and range is it x cannot be 4, -1, or 1??

what is "real zeros"??

and how do u figure the y-intercept...do u just plug 0 into all the X's?

what is the end behaviour?

how do we figure out the symmetry

and the number of turning points..is it 2?

and how do u figure out the approximate coordinates of any local maximum points or local minimum points

THANKS SO MUCH!!

and if u don't mind..can u show me a very brief sketch if its possible?
