Question

Let C be the graph of y=x^2+10x+2. for each of the following eq. state how its graph is related to C, the graph of y=x^2+10x+2.
1. y=x^2-10x+2
2. y=-x^2-10x-2
3. y=-x^2+10x-2
4. x=y^2+10y+2

Answer 1

anyone?

Answer 2

if you factor each one you can see where the x=0 lie and the last term, +/- 2 changes the vertical position of the graph

Answer 3

how do I factor it?
