All right, y equals lnx, lnx squared plus 4 minus 10.

So when i first graft it, i got a graph where i couldn't even see where it intersected the x -axis.
00:33
So i played around with my window until i got a window that i liked.
00:38
X -minn equals 0, x max equals 100, and then x scale equals 10, and then i left all the y is the same.
00:56
So y -min, negative 10, y -max, 10, and y -scale 1.
01:12
And then when i graphed it, it looked something like that.
01:31
So now when i hit my second trace or my calc button, and i go for my zero, which is number two.
01:56
When i hit left bound, i'm looking for anything to the left of this, where it hits the x -axis...
