How am I going to draw the graph of that equation? Can you go into detail?If you need to, sketch a graph of y = x^2 - 12, drawing only the part to the right of (or on) the y-axis.
What values of y are present on your graph? That is the range.
You do see that the graph of y will be parabola - right! The parabola will open up..... and continue....How am I going to draw the graph of that equation? Can you go into detail?
Well, I have the basic education of an IGCSE high schooler (I'm giving O'level next year) , and because of the virus my education is going nowhere so i thought i might as well study on my own.Presumably you have learned some method of graphing. You could plot a few points (e.g. x=0,1,2,3,4), or use facts you've learned about quadratic functions or parabolas, or facts about function transformations (horizontal or vertical shifts), or whatever. I have no idea what you have learned, so I can't give specific advice. But given the sophistication of the problem's notation, I would expect you to be able to do all of the above.
Let us know where you have trouble graphing it, and we can offer help.
