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"]`

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
