NEED HELP SKETCHING GRAPHS

[sagnik24]

[b[/b]Hi I need help with this problem. I am really frustrated and am failing this class even after extra help. Any help would be great.

Sketch the graphs of y = x^2 - 9 , y = 9 - x^2 , and y = absolute value of 9-x^2 on single set of axes.

Can someone please say exact points to plot? And also the rule for this problem like (x,y) to (-x, y)? Thanks in advance

What class are you in and why are you in it?

What tools have you at your disposal? A fancy graphing calculator? Pencil and paper?

How sure are you that you are in the right class.

You get to pick ANY x-value you like. That's why it's called the Independent Variable. Once an x-value is chosen, you can calculate the corresponding y-value.

Please show a few points and we can get started.
