How would you graph Shivam's example?

See you later, have a chore. Take a look around in the help in the meantime.

Something like :

`Plot[y = x^2 + x - 6, {x, 10, -10}]`

?

Yep, that works!

Or even simpler:

`Plot[x^2 + x - 6, {x, 10, -10}]`

What does this part means? {x,-10,10} x-min and x-max?

Let us do some Inequality plots!

This will be hard since I have never graphed an inequality with m, so hold on.

Apparently, it is all done with the command RegionPlot.

Look at this one!

RegionPlot[x^2 + y^2 < 1, {x, -1, 1}, {y, -1, 1}, Mesh -> 10, MeshShading -> {{Automatic, None}, {None, Automatic}}, ColorFunction -> "DarkRainbow"]

Neither do I, that is a complicated one. I just want you to see it. It is amazing.

Just cut and paste

`RegionPlot[x^2 + y^2 < 1, {x, -1, 1}, {y, -1, 1}, Mesh -> 10, MeshShading -> {{Automatic, None}, {None, Automatic}}, ColorFunction -> "DarkRainbow"]`

I typed it. M is so much fun and fascinating.

You must type faster than me. Okay, run it!

Look at that and all done with one command! Can you believe that is an inequality?

This one is a bit simpler but still way too much for my brain.

You can just copy and paste.

RegionPlot[x^2 + y^3 < 2, {x, -2, 2}, {y, -2, 2}]

The blue part is all the points that satisfy that inequality.

We will try one on our own.

Graph the inequality x + y < 10
