I'm very confused and so behind in this course, so I need someone to answer/explain it for me please? I have a DBA tomorrow so my teacher will help me with anything else I don't understand.

This was the first question it's referring to : Your friend runs up to you, scared that he is not ready for the upcoming quadratics test. To help him study, you will create four different quadratic functions. Then demonstrate to him how to rewrite each function as a group of factors, if possible.
The function f(x) is a difference of squares.
The function g(x) is a sum of squares.
The function h(x) is a perfect square trinomial.
The function j(x) can only have a GCF factored out of it.

one of my answers were x^2-9 which i thought i could use

kkutie7 · Answer

yes that is the difference between two squares.

anonymous · Answer

I don't understand how to graph it

kkutie7 · Answer

key feature of your graph would be you second degree x^2 this should give you a pretty good idea of how the graph should look

kkutie7 · Answer

well if you dont recognize it right off the bat you can always plug point in.
y=x^2-9

x^2 produces a parabola|dw:1449118146079:dw|
just not this sloppy
