Question 71722: I have a discussion questio I woul like for some one to explain to me. This is not a graded question or anyhting.
Q: Explain how the graph of can be obtained from the graph of y = x2
this is how the possible answers are presented:
shift the graph of y = x2 left 3 units and down 5 units
. shift the graph of y = x2 left 3 units and up 5 units.
. shift the graph of y = x2 right 3 units and down 5 units
shift the graph of y = x2 right 3 units and up 5 units.

Question 71858: Here is another one that is not explained in the 8 books that I have. At least not good enough whereas I can make sense of it.
the degree three polynomial f(x) with real coefficients and leading coefficient 1, has 4 and 3 + i among its roots. Express f(x) as a product of linear and quadratic polynomials with real coefficients.
Possible answers:
f(x) =(x+4)(x^2 + 6x +10)
f(x) =(x-4)(x^2 -6x -9)
f(x) =(x-4)(x^2 -6x +10)
f(x) = (x-4)(x^2 -6x +9)
Thanks to anyone who can possibly explain this to me.
