Question

I will award a medal!! please help!

Answer 1

I need help on how to graph all of my send degree functions:
Quadratic equation 1) f(x) = x2-9
Quadratic equation 2) g(h) = x2 + 4
Quadratic equation 3) h(x)= (x+ 4)(x+4)
Quadratic equation 4) j(x) = 24x2+8x + 2

Answer 2

Do you know how to graph quadratic equations?

do you know what the graph of \[x^2\] looks like?

Answer 3

Make a function table and put in different numbers for x, and then graph them. See if that works.

Answer 4

okay I will

Answer 5

and no I have no idea what the graph of x^2 looks like

Answer 6

okay I just looked up what it looks like and I get it now. Now what do I do with -9 in the equation? Would I make the point 0,-9 and then graph x^2?

Answer 7

Yes. That's for the first quadratic equation. Remember that the graph has to pass through points (-3,0) and (3,0) as those are your values of "x" when "y" is zero as defined from your equation if you were to solve for "x".

Quadratic equations are easily modified or transferred depending on the their equations. If you need more help, I would advise looking on youtube and search up "Graphing Quadratic Equations". There should be plenty of info on there to help you.

Answer 8

Thanks a lot! I got a lot of help from @DeadShot earlier on this and he helped me work it out.
