So in this problem, we are asked to sketch a parametric function.
00:07
And so we know we have x is equal to negative t, and y is equal to t squared plus 1.
00:17
Y is equal to t squared plus 1.
00:19
And we have t from negative 1 to 2.
00:24
So we have negative 1, 0, 1, and 2.
00:27
And so let's start with with x first.
00:29
So if x is the negative of t, so we have 1, 0, negative 1, and negative 2.
00:38
And so let's do our y.
00:41
So we have 1 squared, which is 1.
00:43
1 plus 1 is 2.
00:46
From 0 plus 1, so we have 1.
00:50
Same thing is 1 squared plus 1 is 2, and 2 squared is 4, 4 plus 1 is 5.
00:57
And so we can sketch this if we say we know that x is from 1 to or negative 2 to 1.
01:07
Well, we know we can say, okay, well, we have from negative 2 to 1, negative 2, negative 1...
