Question

@mathmale  Good evening, could you once again help me?

mathmale · Answer

Certainly!  But I do need to finish helping another student.  
Why don't you go ahead and post your math problem in the meantime?

nicole143 · Answer

Okay! And thank you! Just number 69.

nicole143 · Answer

I know you won't be able to do much with showing me the graphing part, if you could help with the other bits I think I'll be able to mark the points of the graph(:

mathmale · Answer

Nicole, I trust you know how to graph y=x^2.  Could you take advantage of that knowledge to graph -x^2?  -5x^2?  I'll be back.

nicole143 · Answer

Yes, filling in for x and then solving for y.

mathmale · Answer

Nicole, you can certainly do that.  But it's much faster just to remember the shape of a basic quadratic function (y=x^2) and start from that shape.  No tables of values needed.

nicole143 · Answer

I do not know that :/
