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?
