I can't really show you on this calculator.
00:04
I'm going to try my best to explain what i'm doing.
00:10
So what we have going on with the plus in here is that we have an ellipse.
00:15
So what that tells me is with this being x squared and y squared, that's going to be centered at the origin, the square root of 40, yeah, square to 49 is 7.
00:28
So this is about 7 .1.
00:31
That's how high up the graph goes.
00:34
And then the square root of 25 is 5.
00:36
So that's how far to the right this graph goes.
00:40
So just lamely drawing in here the ellipse.
00:46
And then i'm going to go to the calculator because when you go to a calculator and i guess you just have to solve for y, you have to think about how you have to subtract x squared over 25 to the right side.
00:59
And then you have to multiply everything by 50.
01:03
So i'll just go ahead and put times 50 here, but you can distribute if you want.
01:08
And then to solve for y, you have to square root.
01:11
So in my calculator, it will only tell me the top half of this ellipse.
01:17
So if i want the bottom half, i also have to graph this.
01:21
And again, you can distribute if you want minus 2x squared because 50 divided by 25 is 2.
01:28
So a positive version and a negative version.
01:30
But then they also give you the other equation, which is a parabola, y equals negative x squared plus 10x minus 13...
